Puka Nacua caught 14 passes for 150 yards and a touchdown in Sunday’s 20-13 win at Washington, then hurt his right knee on the Rams’ last offensive snap. Sean McVay said Monday that the team will likely put him on injured reserve, per the Rams’ website. The question for fantasy managers is whether he makes it back for the fantasy playoffs.

Puka Nacua knee injury: what was reported

MCL and PCL sprain plus turf toe: out Week 10 and likely headed to IR. If the move happens this week, Week 15 on Dec. 20 is the earliest he can play.

The play was a third-and-11 handoff with 1:44 left. Nacua gained 5 yards and took a hard hit, per CBS Sports. He got up, but ESPN’s Adam Schefter reported Sunday night that he would have an MRI on Monday and that the Rams did not believe he had torn his ACL.

McVay gave the results Monday: sprains of the MCL and PCL, plus turf toe. “We’re thinking it’s going to be at least a month,” he said, and he called IR a strong possibility, per therams.com. The Associated Press reported the same diagnosis and timeline and said the toe sprain is in his big toe. McVay also admitted he has replayed the play call “over and over in my head,” per Pro Football Talk. The jet sweep is now on the injury report too, at least in spirit.

As of Tuesday night, the IR move was expected but not announced. Tuesday’s roster moves were Jordan Whittington to IR and the signing of receiver Xavier Smith, per Rams Wire. A player on IR has to miss at least four games. The Rams play at Arizona on Nov. 15, have a Week 11 bye, then face Green Bay on Nov. 25, Kansas City on Dec. 3 and San Francisco on Dec. 13, per the team schedule. That makes Dallas on Dec. 20 the first game he could play, which Athlon Sports also lists as his earliest return.

He has hurt this knee before. Nacua sprained ligaments in the same right knee in 2024, and five of his eight career missed games came that year, per the AP. That 2024 injury was a PCL sprain in Week 1 that sent him to IR, per NFL.com, and he was activated after missing five games, per Fox News. Former NFL team doctor David Chao said before the MRI that a PCL aggravation was his main worry, per Heavy. The Rams have not said whether this sprain hits the same spot as the 2024 one.

Typical timeline for an MCL and PCL sprain

FFD’s knee range comes from Rams team physician Dr. Matthew Matava, speaking for the NFL Physicians Society in an NFL.com explainer. He says the MCL almost always heals without surgery, and many NFL players with MCL sprains return in about two to six weeks, depending on position and severity. That range covers players and sprain grades in general. It is not a forecast for Nacua, and the explainer does not cover PCL sprains or a combined injury like this one.

Three things point Nacua toward the long end of that range. He sprained two ligaments, not one. He has turf toe on top of it, and FFD’s note on toe injuries (an FFD estimate, not a study figure) says turf toe tends to linger and can sap burst even after a player suits up. And his 2024 PCL sprain cost five games. McVay’s month-plus estimate and the IR calendar both point to mid-December.

Re-injury risk

The NFL.com source gives no recurrence rate for MCL or PCL sprains, so there is no study number to quote here. FFD rates knee re-injury risk as moderate, and that label is a judgment call. His own chart says more: this is the second ligament sprain in his right knee in three seasons, and he had already missed two games earlier this year, per the AP. Expect the Rams to ease him back, and don’t count on a full workload in his first game.

What to do with Nacua in fantasy

Hold him, and stash him in an IR slot once your league allows it. Nacua ranks 41st in Doc’s Top 200 and had 70 catches for 715 yards and four touchdowns in seven games, per the AP. A Week 15 return lines up with the first round of many fantasy playoffs, so check your league’s calendar. If you are fighting for a playoff spot and have no IR slot, selling him is fine, but only for a starter who helps you now. Don’t drop him.

The Rams’ pickups are thin. Davante Adams is also on IR with a hamstring injury, and Dave Richard of CBS Sports expects him back no earlier than Week 12. Nacua and Adams have 100 of the Rams’ 120 wide receiver catches this season, per the AP, so a lot of targets are up for grabs. Konata Mumpfield is the top healthy receiver, with 11 catches for 162 yards and a touchdown, per DraftKings Network, and he led the remaining receivers in slot snaps through Week 8, per Athlon Sports. He is a deep-league add, not a weekly starter.

Tyler Higbee is the safer target. He has 39 targets this season and played 80% of the snaps in Week 9, per Athlon, and DraftKings Network would rather start a Rams tight end than Mumpfield. Tutu Atwell averaged 6.8 targets a game when Nacua missed five games in 2024, per CBS Sports, which makes him a cheap stash. Athlon also expects more receiving work for Kyren Williams (20th in Doc’s Top 200) and Blake Corum (83rd). If you need a real starter, look outside Los Angeles: CBS Sports names Tank Dell and Caleb Douglas as waiver options.

What to watch this week

Watch for the IR move first. The four-game clock starts once the Rams make it, and many fantasy platforms only open an IR slot to players with an IR or Out tag, so check your league’s rules. If the Rams hold off instead, Nacua will show up on the practice report, and Did Not Participate tags Wednesday through Friday would confirm he is out for Arizona.

Then watch the replacements. The first Rams practice report for the Cardinals game comes Wednesday, Nov. 11. Look for any new designation on Higbee or Mumpfield. Tight end Terrance Ferguson pulled a hamstring in practice Friday, and McVay expects him to miss a couple more weeks, per therams.com, so a limited or full tag for Ferguson would be early news. If the Rams open a 21-day practice window for Adams, the December target picture changes again.

Track his practice reports all week on the FFD Injury Report.
