Sam Bradford's high ankle sprain injury could keep the Rams' quarterback out of this weekend's game against the Cowboys.

Sam Bradford suffered a high-ankle sprain injury last week, and the St. Louis Rams quarterback's status for this Sunday is still uncertain.

Bradford's injury came during the Rams' 24-3 loss to the Green Bay Packers last Sunday. Bradford is wearing a walking boot on his left foot, and backup quarterback A.J. Feeley will practice with the starting unit Wednesday, head coach Steve Spagnuolo told reporters Monday.

The injury is reportedly more serious than the Rams had originally thought, and it's one that makes Spagnuolo nervous about his quarterback Bradford's status this weekend as the Rams take on the Dallas Cowboys.

I think you're always concerned when you see your quarterback in a boot, Spagnuolo told reporters. In my experience with the high-ankle sprains, you just never know how long they're going to take. Fortunately, it's not the plant foot, so that helps a little bit. But my limited knowledge about throwing the football quarterback-wise is, it is from the bottom up. So you still need your legs and ankles to throw the ball effectively.

Bradford plants with his right foot, but he still would sacrifice lost mobility with the injury if he were able to play this weekend.

Bradford will not practice Wednesday, but look for the Rams to keep a decision to the latter portion of the week on this one.

The guess? On an 0-5 team, there's no reason Spagnuolo should risk further complications and have Bradford play this week. It seems like the logical move, even if it hurts with a brand-new weapon available in wide receiver Brandon Lloyd, who was acquired from the Denver Broncos on Monday.

Feeley is a not-so-capable backup that will stunt the Rams' passing game this week. He has a career 69.3 passer rating, 27 touchdowns and 29 interceptions. If Feeley gets the start and Bradford can't go, look for a run-heavy attack predicated by Stephen Jackson.
