Indianapolis Colts running back Trent Richardson has admitted that Donald Brown deserves to be starting ahead of him as he did on Sunday.

Richardson, who until the recent win over the Tennessee Titans had never played backup in his career, said that he would continue to work hard in practice to win back his place.

"It's only fair that Donald be the starter, especially with the production he's been putting up," Richardson told the club's official website. "He's been playing good ball.

"When I first got here, people thought it was a two-headed monster but I said it was always a three-headed monster. Donald's been doing a good job. I think he deserves every bit the starting position.

"Will my role change? I doubt it. I don't think it's going to change. I'm still going to go in. I'm still going to get my reps. The coaches tell me nothing is going to change. Donald's starting the game. He deserves it."

Richardson joined the Colts this season from the Cleveland Browns.
