Cleveland Browns rookie running back Trent Richardson is scheduled to have arthroscopic knee surgery Thursday to remove a "hang nail particle" of loose cartilage in his left knee, but he is expected to be back before the regular season opener.
Coach Pat Shurmur confirmed the procedure Wednesday.
The small particle, which has caused swelling, was found after an MRI on the knee and is expected to be operated on by Dr. James Andrews after a final evaluation.
Richardson's injury is reportedly not related to the torn meniscus he had while playing at Alabama during the BCS championship game victory over LSU. Richardson had surgery for that injury in February.
A team source told ESPN that Richardson could go without the surgery but the decision to have it was the consensus opinion.
He is expected back in two weeks, so he could make it back in time to play in one or two preseason games.
A statement by the team said the No. 3 overall pick in the April draft "is traveling to Pensacola, Fla., where he will have his left knee further evaluated by Dr. James Andrews (Thursday)."
