EARTH CITY, Mo. -- St. Louis Rams coach Jeff Fisher said Saturday that a decision on rookie running back Todd Gurley's status for the season opener has already been made.

"Gurley’s not going to play this week," Fisher said.

So Gurley, who is still recovering from a torn ACL suffered last November, will have to wait before he makes his NFL game debut. Gurley has continued to participate fully in practice though he's still off-limits for contact.

The Rams have not put a specific date on Gurley's return but the belief has been that he might start getting carries at some point before the Week 6 bye and then take on a larger role after that. In the meantime, the Rams still have to sort through their options with projected Gurley replacement Tre Mason battling a hamstring issue.

Fisher said last week that Mason would be questionable for the first game against the Seahawks but offered a small update on Mason's progress.

“Tre’s doing good," Fisher said. "He had two treatment sessions today, and he’s doing well. So we’ll see how he is during the week."

With or without Mason in the lineup, the Rams will likely have to lean on Benny Cunningham to play a larger role against the Seahawks on Sept. 13.
