The potential loss of MLB Channing Crowder would be a serious setback for the Miami Dolphins and their chances of getting into the AFC playoffs.

The Miami Dolphins official Web site reports LB Channing Crowder did not travel with the team for Sunday’s game against the New York Jets and is listed as out.

Dolphins starting LB Akin Ayodele is listed as questionable for Monday night’s matchup with the Colts. Ayodele was a full participant in Thursday and Friday practices, but he was held out today with what the team described as a back injury.
