Several of fantasy football's biggest names enter NFL Week 5 with injury concerns, but the implications extend beyond whether those players are active on Sunday.
From Philadelphia's depleted backfield and offensive line to uncertainty surrounding Justin Jefferson's chemistry with Kyler Murray, fantasy managers face difficult lineup decisions that could impact their Week 5 matchups.
Here are five key injury situations and what they mean for fantasy football.
1. Saquon Barkley and Tank Bigsby, Eagles — Backfield Injuries
Barkley has missed consecutive practices with a right hamstring injury and is considered week-to-week. Bigsby is on injured reserve and will not play against Jacksonville, leaving Will Shipley in position to handle a significant workload if Barkley is ruled out.
Fantasy Impact: Shipley could see plenty of opportunities, but volume doesn't necessarily guarantee production.
Philadelphia's offensive line looks considerably different this season. The Eagles traded center Cam Jurgens, Lane Johnson retired and Landon Dickerson is on injured reserve. Those losses raise questions about how effectively Philadelphia can establish its running game.
The passing offense is also without DeVonta Smith, potentially allowing Jacksonville to focus more attention on stopping the run.
Shipley could be a volume-based fantasy starter, but his efficiency and touchdown opportunities remain major concerns.
2. Ja'Marr Chase and Tee Higgins, Bengals — Receiving Corps Injuries
Chase returned to practice Thursday as a limited participant while working through concussion protocol, an encouraging development after missing Wednesday's session.
Higgins, meanwhile, has missed consecutive practices with adductor and neck injuries, putting his availability for Sunday's matchup against Miami in question.
Fantasy Impact: Chase remains a must-start fantasy receiver if he clears concussion protocol, regardless of Higgins' status.
If Higgins is ruled out, Joe Burrow could lean even more heavily on Chase, potentially increasing his target share and fantasy ceiling.
If Chase cannot play, Higgins would become Cincinnati's primary receiving option, provided he is healthy enough to suit up.
The biggest concern would be both receivers missing Week 5, forcing Burrow to rely on secondary receiving options.
3. Lamar Jackson, Ravens — Left Ankle
Jackson has missed consecutive practices with a left ankle injury, leaving his availability for Sunday's matchup against Atlanta uncertain.
If Jackson cannot play, Tyler Huntley is expected to start. Huntley has starting experience, but his playing style could change how Baltimore's passing offense operates.
Fantasy Impact: Zay Flowers remains a must-start fantasy receiver regardless of which quarterback starts, but his production could look considerably different with Huntley.
With Jackson, Flowers benefits from downfield opportunities and passes delivered in stride, averaging 14.5 yards per reception.
With Huntley, the passing game tends to feature quicker, shorter throws. Flowers averages 7.5 yards per catch in that situation, although his catch rate climbs to 79.2%.
Huntley could provide Flowers with a reliable reception floor, particularly in PPR formats, but his yardage and big-play ceiling would likely decrease.
Fantasy managers should continue starting Flowers while adjusting expectations if Jackson is unable to play.
4. Justin Jefferson, Vikings — Ankle
Jefferson was limited in practice Wednesday and Thursday as he works toward returning from an ankle injury that sidelined him in Week 4.
Minnesota enters Week 5 undefeated at 4-0, but its passing offense ranks last in the NFL. Jefferson has also played just 17 snaps with quarterback Kyler Murray this season.
Fantasy Impact: Jefferson remains difficult to bench if active, but there is considerable uncertainty surrounding what Minnesota's passing offense can produce.
If Jefferson cannot play, T.J. Hockenson could be the biggest beneficiary.
Hockenson recorded 13 receptions in Jefferson's absence last week as Minnesota relied heavily on its running game and shorter passes rather than attacking downfield.
That approach could continue against New Orleans if Jefferson remains sidelined, giving Hockenson significant value in PPR formats.
Jordan Addison could also see additional opportunities, but last week's production suggests Hockenson is the more compelling fantasy option if Jefferson misses another game.
Even if Jefferson returns, his limited playing time with Murray makes their chemistry one of the biggest unknowns entering Week 5.
5. Ladd McConkey, Chargers — Foot
McConkey missed practice Wednesday and Thursday with a foot injury, putting his availability for Sunday's matchup against Denver in question.
However, his injury is only one part of a larger problem for the Chargers, whose offense has been a significant fantasy disappointment through four weeks.
Los Angeles is dealing with multiple injuries along its offensive line. Rashawn Slater is expected to miss four to six weeks, although he has not yet been placed on injured reserve. Joe Alt is expected to miss Week 5 with a neck injury, while center Tyler Biadasz is out for the season.
Fantasy Impact: Even if McConkey returns, there are legitimate concerns about the Chargers' ability to generate consistent offensive production.
The offensive line injuries could force Justin Herbert to rely on quicker throws and shorter passing concepts, limiting opportunities for explosive plays.
That could benefit short-area targets in PPR formats, but it also raises concerns about McConkey's overall yardage and touchdown ceiling.
The matchup provides some optimism, as Denver's defense has struggled through the first four weeks.
McConkey remains a potential fantasy starter if active, but his foot injury and the Chargers' protection issues make him a riskier option than expected entering the season.
Herbert's fantasy outlook also takes a hit with multiple starting offensive linemen unavailable, even against a struggling Denver defense.
