John Harbaugh has said that the Baltimore Ravens need to increase Ray Rice's workload.

The running back had just five carries during the Super Bowl champions' 23-20 defeat to the Buffalo Bills last Sunday.

The head coach told the team's official website: "We need to get Ray involved. We need to get Ray involved in every single way, pass game, run game, every single way.

"It's definitely going to be important for us. We want to do that every week, and obviously, we did not do a good job of that last Sunday.

"If you watch the tape, you will see him in pass protection more often than not. He got held in there in protection, blocking linebackers when they were bringing pressure."

The Ravens face the Miami Dolphins this weekend.
