Zac Stacy injury: Rams RB hurts ankle in Monday loss

St. Louis Rams running back Zac Stacy injured his left ankle on the final drive of Monday's loss to the Seattle Seahawks. The rookie runner will have an MRI on his ankle on Tuesday to determine the full extent of the injury.

Stacy was seen on the sidelines getting his leg wrapped in tape after he initially left the game with less than five minutes to play. He was walking around in obvious pain. However, Stacy was ready to come back into game, and finally did on the last play of the night ... where Brian Schottenheimer had him lined up wide for some inexplicable reason.

A fifth-round pick out of Vanderbilt, Stacy carried the ball 26 times for 134 yards, the first Rams rusher to top triple digits in a game this season. It was a breakthrough performance that kept the vaunted Seattle defense on it heels for most of the game.

The Rams will know more about Stacy's status after tests on Tuesday. Suffice it to say, he's a crucial piece of the puzzle, especially with the backup quarterback now thrust into the starting role.

Stacy talked briefly to none other than Tony Softli after the game. He didn't say much about his injured ankle, but did talk about the rest of his day on the field. Listen:
