Indianapolis, IN (SportsNetwork.com) - The injury that knocked Indianapolis Colts running back Ahmad Bradshaw out of Sunday's loss to New England has been determined to be a fractured fibula that is likely to sideline the team's leading rusher for the remainder of the season.

Colts head coach Chuck Pagano revealed the diagnosis during his Monday press conference, then stated that Bradshaw will visit a few more specialists before the team decides whether or not to place him on injured reserve.

Bradshaw sustained the injury when being stopped just short of the goal line on a short run early in the fourth quarter of Indianapolis' 42-20 home loss to the Patriots. The veteran back was later spotted on crutches with his left leg in a protective boot following the game, according to the Indianapolis Star.

The two-time 1,000-yard rusher was limited to just three games last season -- Bradshaw's first with Indianapolis after a six-year tenure with the New York Giants -- by a neck problem which required surgery. He was having a strong campaign for the AFC South-leading Colts this year, however, compiling a team- best 425 rushing yards with two touchdowns on 90 carries and adding 38 catches totaling 300 yards and six more scores.

Of Bradshaw's eight NFL seasons, he has been able to play in 16 games only once.
