Sam Bradford ahead of schedule if he plays

The St. Louis Rams have listed quarterback Sam Bradford as questionable for the second time this season.

Recovery times for high-ankle sprains can be unpredictable, coach Steve Spagnuolo has repeatedly said, but if Bradford returns Sunday, he'll beat reasonable expectations.

Three Cleveland Browns quarterbacks suffered high-ankle sprains last season. The youngest of the three, Colt McCoy, played in a game 28 days later. The oldest, Jake Delhomme, was forced into action prematurely after a 28-day recovery period. He played two quarters and still wasn't right a month later. The Browns' other quarterback last season, Seneca Wallace, returned to practice 31 days after suffering his high-ankle sprain.

Bradford was injured during an Oct. 16 game at Green Bay. Bradford did not play the next week after the Rams listed him as questionable. In retrospect, the team's optimism that week could have reflected Bradford's determination to play more than his realistic chances for getting onto the field so quickly. The team reassessed the injury and held out Bradford against New Orleans in Week 8.

Bradford practiced on a limited basis Friday.

There has been no clear pattern for players the Rams have listed as questionable. Seven of 13 did not play after appearing as questionable on previous Fridays this season. An eighth, Steven Jackson, was limited to only 14 offensive snaps after being questionable for Week 3.

The chart shows the players St. Louis has listed as questionable on Fridays previously this season, their injuries, whether they played and how much they played.
