Rams wide receiver Danny Amendola may have broken his collarbone during Thursday night's game with the Arizona Cardinals, according to Jason LaCanfora of CBS Sports. Amendola left tonight's game against the Cardinals in the second quarter with an apparent shoulder injury after diving for a pass attempt. He was quickly taken to the team's locker room and has not reappeared since. LaCanfora reports that team officials are worried the veteran receiver broke his collarbone, but will not know the precise nature of the injury until tests are conducted Friday.

Amendola has been the Rams' leading receiver this season by a wide margin, with 31 catches for 351 yards and two touchdowns entering tonight's game. He had caught one pass for 44 yards against the Cardinals before being injured. Amendola was also the team's primary punt returner.

Despite losing Danny Amendola, the Rams lead the Arizona Cardinals 10-3 early in the third quarter.
