The Browns released a statement Thursday confirming reports that RB Trent Richardson underwent surgery.
"Trent Richardson underwent a successful routine arthroscopic procedure today on his left knee," Browns head coach Pat Shurmur said. "It was performed by Dr. James Andrews in Pensacola, Fla.
"We anticipate that Trent will make a speedy recovery, and we are hopeful that he will be ready for our Week One game against Philadelphia."
Cleveland selected Richardson with the third overall pick in this year's draft, and he is expected to be the team's featured back.
