Status update, Sep 29: since this was published, Kyler Murray is now cleared to play (concussion protocol); Sam Darnold is now cleared and the Week 4 starter (glute); Ladd McConkey is off the injury report; TreVeyon Henderson is off the injury report. See the current injury report →

Week 1 is officially in the books after Kansas City closed it out Monday night, and the two headlines from that game — a clean bill of health for Patrick Mahomes and a monster debut for Kenneth Walker III — are as good as this board has had all week. The other side of Tuesday morning is Dylan Sampson: the Browns running back’s knee injury, murky since Sunday, has hardened into a real absence. Layer in the medical reports that landed late Monday on A.J. Brown, Brock Bowers, Sam Darnold and TreVeyon Henderson, and there is a full Week 2 picture to sort through this morning.

🟢 Likely = expected to play a full role, 🟡 Questionable = real uncertainty, 🔴 Out = not playing Week 2 as of this morning.

Quarterbacks

🟢 Likely — Patrick Mahomes (Chiefs): the closing act of Week 1 was also its best injury news. Nine months removed from a torn ACL and LCL, Mahomes went 15-of-27 for 184 yards and two touchdowns and added a 15-yard rushing score in Kansas City’s 31-10 win over Denver, moving comfortably in the pocket and showing no hesitation on his knee all night. The Chiefs’ lone absence was left tackle Josh Simmons (back), who sat out as expected; nothing else came out of the game injury-wise for either side. Fantasy Action: start Mahomes with confidence in every format — the health question is answered, and the only thing left to monitor is the shorter first outing under his belt.

🔴 Out — Sam Darnold (Seahawks): Seattle’s own Monday-evening statement called this a “very unique soft-tissue injury” in the glute rather than the hip itself, which is better news than Sunday’s uncertainty suggested, but the club still described the absence as short-term with no return date attached. Drew Lock holds the job in the meantime. Fantasy Action: bench Darnold for Week 2 and stream a quarterback rather than rostering Lock in anything shallower than a two-quarterback league.

🔴 Out — Kyler Murray (Vikings): still working through the concussion protocol after leaving Sunday’s opener in the first quarter, and Minnesota has not said whether he clears it in time for Week 2 against Chicago. Carson Wentz finished the opener and would start again if Murray is not cleared. Fantasy Action: have a streaming option ready in case Murray is held out again, and check Wednesday’s practice report before trusting either quarterback in your lineup.

Running Backs

🟢 Likely — Kenneth Walker III (Chiefs): the $45 million free-agent signing looked worth every dollar in his Kansas City debut — 23 carries for 173 yards and a touchdown on the ground, plus three catches for 18 yards and a receiving score, good for 191 yards from scrimmage and two total touchdowns in the win over Denver. Fantasy Action: start Walker as a locked-in RB1 the rest of the way; this was a workload and a role, not a one-game spike.

🔴 Out — Dylan Sampson (Browns): Sunday’s vague “knee injury, no official diagnosis” has turned into real bad news. ESPN’s Jeremy Fowler reports Sampson is expected to miss significant time after hurting his left knee on a first-quarter kickoff return against Jacksonville, and a serious enough evaluation that a trip to injured reserve is a real possibility. Sampson was Cleveland’s change-of-pace and return back rather than the starter, so the fantasy consequence runs almost entirely toward Quinshon Judkins, with Raheim Sanders and practice-squad back Jaleel McLaughlin the only depth behind him. Fantasy Action: start Judkins as an every-week RB2, drop Sampson in shallow leagues, and only stash him if your bench has the room to wait out a real IR stint.

🟡 Questionable — TreVeyon Henderson (Patriots): practiced Monday for the first time since August 24, working footwork and ball-security drills alongside Rhamondre Stevenson, with head coach Mike Vrabel framing it as an evaluation rather than a clearance. It is enough to move Henderson off this board’s Out tier and into a live call for Week 2 against Pittsburgh, but Stevenson still holds the starting job for now. Fantasy Action: add Henderson to your bench if he is available, but do not start him over Stevenson until Wednesday’s practice report shows a real workload.

🔴 Out — Isiah Pacheco (Lions): Monday’s medical update turned a manageable timeline into a lost season for fantasy purposes. NFL Media’s Ian Rapoport reports Pacheco has had back surgery, performed by spine surgeon Dr. Robert Watkins IV, with Detroit targeting an early-December return — a jump from a four-game injured-reserve stay to roughly 12 weeks. Jahmyr Gibbs remains the lead back regardless. Fantasy Action: drop Pacheco in all but the deepest dynasty formats; he is not a factor again until December at the earliest.

Wide Receivers

🔴 Out — A.J. Brown (Patriots): the high-ankle sprain is now a confirmed six-week absence rather than the four-to-six-week range New England left open on Friday, with Rapoport reporting no surgery is planned. Vrabel confirmed Monday that Brown is on the standard four-game injured-reserve window, which makes Week 5 the procedural floor and the six-week estimate the realistic target — call it Week 7. DeMario Douglas, Mack Hollins and Romeo Doubs share the vacated target share in the meantime. Fantasy Action: hold Brown as an IR stash if you have the roster spot, but do not expect him back before Week 7.

🟡 Questionable — Ladd McConkey (Chargers): what the Chargers described Sunday as a chest contusion has been re-labelled a possible rib injury, with Rapoport reporting X-rays and an MRI ordered Monday afternoon rather than a simple wait-and-see. Quentin Johnston is the clear next man up if McConkey misses time. Fantasy Action: hold McConkey through Wednesday’s imaging results rather than benching him preemptively, and have Johnston ready as a bench stash regardless.

🟡 Questionable — Zay Flowers (Ravens): the aggravated hamstring that ended his 5-catch, 150-yard, one-touchdown day early is being described as day-to-day, with Rapoport noting Flowers would have gone back in Sunday had it been a playoff game. That points toward a real chance he plays Week 2 against New Orleans rather than a multi-week absence. Fantasy Action: pencil Flowers in as a flex for now, and keep Rashod Bateman as the handcuff pivot if Wednesday’s practice report goes the wrong way.

Tight Ends

🟡 Questionable — Brock Bowers (Raiders): one week removed from a knee meniscus trim, ESPN reports Las Vegas believes there is a realistic chance Bowers plays Week 2 against the Chargers — a much faster turnaround than the board’s earlier “two-plus weeks” framing suggested. Michael Mayer has handled the starting reps in the meantime and remains a viable streaming option until Bowers is officially cleared. Fantasy Action: add Bowers back if he cleared your waivers, but keep Mayer rostered as insurance until a Wednesday or Thursday practice report confirms the return.

Wednesday’s practice reports are the next real signal for every name on this board — especially McConkey’s imaging results, Henderson’s workload alongside Stevenson, and whatever comes out of Cleveland on Sampson. Check the full Week 2 injury report for the complete, continuously updated list.
