Los Angeles Rams wide receiver Cooper Kupp left Sunday’s game against the Seattle Seahawks with an apparent knee injury.

Kupp suffered the injury on a first-and-10 play in the fourth quarter with the Rams leading, 26-24. Kupp planted on a route and immediately fell to the ground, clutching his left knee.

He did not return to the game, and head coach Sean McVay was not optimistic about his status after the game.

“Yeah, I don’t think it’s very good,” McVay told reporters.

NFL Network reports that Kupp is scheduled for an MRI on Monday.

Kupp entered the game as the Rams’ third-leading receiver with 527 yards on 35 catches. He is quarterback Jared Goff’s favorite end zone target, leading the team with six touchdown catches on the season.
