The Denver Broncos were hoping to have a healthy J.D. Walton start at center in 2013, but it appears that plan will have to be pushed back once again.
According to Jeff Legwold of The Denver Post, Walton had another surgery on his injured ankle and is likely to miss the 2013 season.
The injury to Walton leaves the Broncos with only the unproven Quentin Saulsberry and Philip Blake on the roster at center. The team will likely comb through the available free agents for a veteran to snap the ball to Peyton Manning.
Walton originally hurt his ankle in Week 4 of the 2012 season, but the Broncos had wisely signed veteran center Dan Koppen to a one-year contract and he ended up starting 12 games.
