Cleveland Browns running back Trent Richardson is scheduled to have arthroscopic surgery Thursday to remove loose cartilage from his left knee that has been bothering him during training camp, reports ESPN.com.
The surgery, which is described as removing a "hang nail particle" in the knee, will allow Richardson to return to play before the Browns season opener. The Browns will start their season at home on Sept. 9 against the Philadelphia Eagles.
The small particle, which has caused swelling, will be "cleaned up" by Dr. James Andrews after it was detected in an MRI. Dr. Andrews will do a final evaluation before he is expected to perform the minor surgery.
Earlier, the Browns said Richardson would travel to Pensacola, Fla., to have his left knee further evaluated by Andrews.
