ESPN.com: Trent Richardson to Have Surgery

ESPN.com is reporting Cleveland Browns running back Trent Richardson is going to have an arthroscopic procedure on his left knee, perhaps as early as tomorrow.

The procedure is to remove a particle causing irritation to cartilage.

It is not related to the injury suffered by Richardson which required scoping back in February.  He suffered a torn meniscus with that injury.

This procedure is not considered invasive and the team says Richardson should be back before the start of the regular season.
