Rams WR Danny Amendola, who left Thursday night's win over the Cardinals after attempting to make a diving catch in the second quarter and did not return, reportedly suffered a broken collarbone.

Amendola had a 44-yard catch on the Rams' opening drive, which led to a TD pass from Sam Bradford to Lance Kendricks and an early 7-0 lead. Amendola entered the game with 31 receptions, second in the NFL, with two TDs and an 11.3-yard average.

This is the second season in a row that Amendola has suffered a serious injury. He missed nearly all of last season after dislocating his left elbow early in a Week One loss to the Eagles.

The Rams also lost safety Quintin Mikell (head), FB Britt Miller (ankle) and LB Mario Haggan (thigh) to injuries Thursday night.
