Puka Nacua had a monster game for the Los Angeles Rams during Sunday’s 20-13 win over the Washington Commanders. The wide receiver hauled in 14 passes for 150 yards and a touchdown, and added another 20 yards on a pair of rushing attempts, as the Rams moved above .500 on the season.

But now Los Angeles is holding its collective breath, as Nacua is set for an MRI after injuring his knee on the Rams’ final offensive play of the game.

According to Adam Schefter of ESPN, Nacua suffered a knee injury on the Rams’ final offensive snap, and will undergo an MRI on Monday to “determine the extent of the injury.” Schefter and Mike Garafolo are reporting that the team “does not elieve he suffered a torn ACL,” but that the “imaging Monday will tell more.”

The play was on of Nacua’s two rushing attempts on the game, an end-around design that was held to a short gain. Nacua did get up right after the tackle, but walked back to the sideline rather gingerly.

Los Angeles plays the Arizona Cardinals in Week 10, before a bye week in Week 11. Their next game is the new “Thanksgiving Eve” contest on Wednesday, November 25 against the Green Bay Packers.
