MIAMI (AP) - Miami Dolphins running back Arian Foster has been ruled out of Sunday's game against Cleveland because of a groin injury.
Foster's absence means second-year pro Jay Ajayi will likely make his first NFL start. Rookie Kenyan Drake is also expected to see significant action.
Dolphins running backs have netted only 82 yards in the team's first two games, both losses.
Center Mike Pouncey was ruled out Friday for the third week in a row as he recovers from a hip injury.
