The Indianapolis Colts announced Friday that running back Ahmad Bradshaw is out at least two weeks. He is considering season-ending neck surgery, though the severity of his injury remains unclear.
Bradshaw has been out since he was injury Sept. 22 at San Francisco.
"Ahmad has seen several specialists, collected a lot of information," coach Chuck Pagano said. "He's going to take the next couple of weeks to decide where he's going to go with this (neck injury). I don't know ultimately where that is. It will be up the Ahmad and doctors to come up with a final decision with what's going to transpire.
"It's a matter of calming things down, taking time to figure out where we are and to make the right decision. Ultimately, it's what is best for Ahmad."
The Colts signed the 27-year-old Bradshaw to a one-year deal in June. Because of durability questions -- Bradshaw had multiple foot surgeries as a member of the New York Giants -- his deal is laden with incentives.
Trent Richardson, acquired from the Cleveland Browns, and backup Donald Brown combined for 125 yards last week at Jacksonville. The team also has fullback Robert Hughes in the backfield. The Colts signed him on Monday.
Also, the team signed safety Larry Asante on Friday. Asante rejoins the Colts after the team waived him at the end of the preseason. He replaces Joe Lefeged, who was released Thursday night.
