Former Red Raider and current St. Louis Rams wide receiver Danny Amendola injured his right shoulder on a diving attempt at a catch in the second quarter against Arizona on Thursday night.

He never returned to the game, reappearing on the sidelines with his arm in a sling.

Rams head coach Jeff Fisher had little to say regarding the injury calling it a “competitive issue”, but did say he’d have an injury report on Wednesday regarding Amendola but said he was certain the wideout would miss the Oct. 14 game at Miami.

According to CBSSports.com's Jason La Canfora, Amendola's collarbone is not broken. Instead, he has a shoulder separation, and it's likely only a six-week injury, but could be shorter.

Through five games, Amendola leads the team with 31 receptions and 351 yards. Austin Pettis and Steve Smith will likely get the opportunity to take over his snaps.

The Rams beat the undefeated Arizona Cardinals 17-3.
