Week 1 giveth, and Week 1 taketh away. The first Sunday of the fantasy football season always produces a few breakout performances, a few managers convinced they have already won their league, a few hating life, and a handful of injuries that force everyone to start digging through the waiver wire.

This week, the injury list is particularly interesting. A.J. Brown is headed to injured reserve, Jordan Mason is on IR, and several other fantasy starters are questionable for Week 2. That means opportunity is about to knock for some players sitting much lower on draft boards.

But remember: “next man up” does not automatically mean “fantasy starter.” Sometimes the next man up is merely the next man up.

Here are the players worth monitoring.

A.J. Brown — WR, New England Patriots

Injury: High-ankle sprain
Status: Placed on IR; expected to miss approximately six weeks

Brown’s Patriots debut lasted less than three quarters before a high-ankle sprain sent him to the sideline. New England subsequently placed him on injured reserve, and the current expectation is that Brown will miss roughly six weeks.

That’s a significant chunk of the fantasy season.

The Patriots’ receiving corps now becomes one of the more interesting situations to watch. Romeo Doubs, DeMario Douglas, Mack Hollins and Kyle Williams are among the players who could see increased opportunities.

Fantasy player to monitor: Romeo Doubs

Doubs is the player I’d watch most closely. He didn’t exactly set the fantasy world on fire in Week 1, catching zero of three targets, but Brown’s absence creates a much larger opportunity than anything Doubs saw in the opener.

Add him if available, but don’t expect Brown production. The Patriots are likely to spread the additional targets around.

Also watch: DeMario Douglas and Mack Hollins.

Nico Collins — WR, Houston Texans

Injury: Hamstring
Status: Week 2 status in jeopardy

The Texans were already dealing with one major hit to their receiving corps before Collins’ hamstring injury. Jayden Higgins is out for the season with a torn ACL, removing one of Houston’s projected contributors before the regular season even got rolling.

Now Collins’ status is in doubt for Week 2. That’s potentially a much bigger fantasy problem than it looks on paper. Houston could suddenly be without its top two perimeter receiving options, leaving C.J. Stroud with a dramatically different supporting cast.

Fantasy players to monitor: Xavier Hutchinson, Kayshon Boutte and Jaylin Noel

This is where things get interesting — and considerably less obvious.

Xavier Hutchinson is probably the first player fantasy managers should monitor for the short term. He has prior experience stepping into a larger role and could see the biggest immediate increase in playing time if Collins sits. He led the team with 6 targets last week.

Kayshon Boutte is another name to watch. He’s a bigger-bodied receiver who could benefit from additional snaps and red-zone opportunities. He was an August edition to the roster and could take time to ramp up.

Then there’s Jaylin Noel, who brings a different skill set and could see his role expand if Houston needs more explosive plays from the receiver position.

The Texans may also compensate for the depleted receiver room by leaning more heavily on the running game and tight ends. Houston targeted 11 different players in Week 1, so don’t expect Stroud to simply pick one receiver and funnel everything Collins and Higgins would have received to him.

PigSkinFantasy takeaway: Hutchinson is the immediate name to monitor, while Boutte and Noel are deeper-league stashes. But this is a situation where watching Week 2 snap counts and routes may be more valuable than blindly throwing FAAB at the first receiver listed on the depth chart.

Zay Flowers/Ja’Kobi Lane — WR, Baltimore Ravens

Injury: Hamstring/Fractured Wrist
Status: Missed practice; questionable/

Lane was placed on IR and will miss a minimum of four weeks. Flowers was initially considered day-to-day, but missing both Wednesday and Thursday practices has made his Week 2 availability considerably less certain.

And this matters because Baltimore’s passing game showed plenty of life in Week 1.

Fantasy player to monitor: Rashod Bateman

Rashod Bateman becomes the obvious receiver to watch. Baltimore doesn’t necessarily need to replace Flowers’ production with one player, though. Lamar Jackson can distribute the ball to Bateman, tight ends and the running backs while continuing to create plays with his legs.

There has also been some discussion of Baltimore potentially adding another veteran receiver, so don’t go crazy spending FAAB on this situation.

Fantasy takeaway: Bateman is worth adding if available, but Flowers’ absence doesn’t automatically turn him into a weekly WR2.

Brock Bowers — TE, Las Vegas Raiders

Injury: Knee/meniscus
Status: Expected to miss one or two games

Bowers underwent a meniscus trim before the season and was expected to miss one or two games. He has not practiced this week.

Fortunately for fantasy managers, this looks much more like a short-term inconvenience than a season-long problem.

Fantasy player to monitor: Michael Mayer

This one is easy. Michael Mayer is the guy.

Mayer has already demonstrated that he can produce when Bowers isn’t on the field. In 2025, more than half of Mayer’s receptions and receiving yards came in games in which Bowers was inactive.

Mayer also enters 2026 with career highs of 35 receptions and 328 receiving yards from last season.

Fantasy takeaway: Mayer is a legitimate short-term TE option while Bowers is out. Just don’t mistake two weeks of opportunity for a changing of the guard.

Kyler Murray — QB, Minnesota Vikings

Injury: Concussion
Status: Limited in practice; still in protocol

Murray suffered a concussion in Minnesota’s Week 1 victory over Green Bay and remains in the NFL’s concussion protocol. He was limited in practice Thursday.

Fantasy player to monitor: Carson Wentz

If Murray cannot clear the protocol, Carson Wentz is the obvious player to watch.

Wentz stepped in during Week 1 and completed 12 of 19 passes for 133 yards and three touchdowns. Most importantly for fantasy purposes, he immediately demonstrated a connection with Justin Jefferson, who finished with eight catches for 92 yards and two touchdowns.

Wentz isn’t suddenly a must-start quarterback for the rest of the season. But if Murray is ruled out and you’re desperate at quarterback?

Wentz becomes interesting. Especially in Superflex leagues.

Joe Burrow — QB, Cincinnati Bengals

Injury: Back tightness
Status: Expected to play

This is the least interesting “next man up” situation on the list — and that’s actually a good thing.

Burrow is expected to play, so fantasy managers shouldn’t be making contingency plans unless his status deteriorates.

If the Bengals suddenly rule him out, Joe Flacco is the backup worth knowing. Cincinnati re-signed Flacco this offseason after he started 10 games for the Bengals in 2025.

And yes, we’ve seen this movie before. But unless Burrow’s back tightness turns into something more significant, Flacco belongs on the watch list, not your waiver claim list.

Ladd McConkey — WR, Los Angeles Chargers

Injury: Ribs/chest
Status: Day-to-day; Week 2 status uncertain

McConkey suffered the injury in Los Angeles’ Week 1 loss and was working off to the side during Thursday’s practice.

The good news is that the Chargers have described the injury as day-to-day rather than something expected to keep him out for an extended period.

Fantasy players to monitor: Quentin Johnston and Tre Harris

If McConkey misses Week 2, Quentin Johnston and Tre Harris would be the primary receivers to watch.

Harris is particularly interesting for fantasy manager. He played two less snaps that Johnston last week, drew the same number of targets and had one more catch. That’s the kind of situation PigSkinFantasy likes.

You don’t necessarily need to start Harris immediately. You want him on your bench before the rest of your league realizes why he matters.

Jordan Mason — RB, Minnesota Vikings

Injury: Fractured thumb
Status: Placed on IR

Mason’s injury is one of the more important fantasy developments of the week.

He carried the ball 15 times for 59 yards and a touchdown in Week 1 before suffering the thumb injury and undergoing surgery. Minnesota subsequently placed him on injured reserve.

Fantasy player to monitor: Aaron Jones

The obvious name is Aaron Jones. Mason’s injury should return a significant portion of the Minnesota backfield workload to Jones, making him a player fantasy managers should be looking to acquire if his rostered percentage or trade cost hasn’t already caught up with the news.

But there’s another name worth knowing.

Deep stash: Demond Claiborne

Demond Claiborne could be the more interesting player to monitor for dynasty leagues and deeper redraft formats.

With Mason headed to IR, Minnesota has an opportunity to give Claiborne more work and see what he can do with it.

Jones is the immediate fantasy beneficiary. Claiborne is the guy you keep an eye on.

Don’t confuse an injury with an opportunity.

The opportunity is only valuable if the player receiving it is actually good enough — and likely to receive enough of the workload — to turn it into fantasy points.

Sometimes the next man up is a breakout waiting to happen. Sometimes he’s just standing there because somebody has to.

That’s why we watch the snaps, routes, targets and touches before we start spending the FAAB.
