DENVER—Broncos center J.D. Walton called a team meeting Monday to apologize to players and coaches for inadvertently snapping the ball to third-string quarterback Brady Quinn, promising to never make the same stupid mistake again. “I’m so sorry. What I did was absolutely wrong and never should have happened,” said Walton, begging the Broncos for forgiveness while nervously surveying the angry faces in the crowd. “I feel terrible and I know I let this entire organization down. Coach Fox has said from day one to never hike the ball to Brady Quinn, but I screwed up big time. I know it isn’t likely, but I hope I can eventually win back your trust and respect.” Broncos head coach John Fox was reportedly furious about the incident and reassured the team’s front office that a “fuckup” of such proportions would never happen in a game situation.
