Stafford missed six games last year with a banged-up left shoulder and right knee. Hill, who took his place in last weekend's 19-14 loss, made six starts for the 49ers last year, winning three.
Colts' Sanders sidelined again
Colts safety Bob Sanders is out indefinitely after he had surgery for a torn right biceps. Since being named the 2007 NFL defensive player of the year, he has played only nine games. In his seven-season career, he has missed more games (49) than he's played (48).
Cowboys' Garrett: It's on me
Cowboys offensive coordinator Jason Garrett is taking the blame for trying an ill-fated play at the end of the first half instead of having Tony Romo take a knee. "It's my fault,'' said Garrett, who called for a Hail Mary from his own 46-yard line with 4 seconds left. After a 10-yard penalty against Dallas, Romo shoveled the ball to Tashard Choice, who fumbled. DeAngelo Hall returned it for a touchdown in the Redskins' 13-7 victory.
Around the league
Cowboys linebacker DeMarcus Ware missed practice because of a head injury but is expected to play against the Bears . . . Browns quarterback Jake Delhomme wore a boot on his right ankle, and his status for Sunday's game against the Chiefs was undetermined. If he can't play, Seneca Wallace will start.
