CLEVELAND -- Browns wide receiver Jarvis Landry suffered a knee injury on the opening drive Sunday and was ruled out against the Houston Texans.
The Browns believe Landry has a sprained MCL. He will undergo further testing, a source told ESPN's Adam Schefter.
Landry caught a 9-yard pass on Cleveland's first snap but then left the field and did not return to the game, which the Browns won 31-21.
The Browns were already without wide receiver Odell Beckham Jr., who has yet to play this season as he returns from last year's knee surgery.
The Browns had another injury scare in the first half when quarterback Baker Mayfield took a shot to his left shoulder while trying to make a tackle after throwing an interception. He briefly went to the locker room but returned in time for Cleveland's next possession and later scored on a 5-yard touchdown run just before halftime.
