San Diego Chargers running back Donald Brown has been cleared to return to practice after missing three games with a concussion.

Brown practiced Wednesday for the first time since being injured in a victory against the New York Jets on Oct. 5.

Says Brown: "It's something you don't want to mess with. You never wish it on everybody."

Brown returns as the Chargers (5-3) are trying to end a two-game losing streak. They visit Miami on Sunday, where the Chargers are 0-7 since their epic overtime playoff victory following the 1981 season.

Running back Ryan Mathews might soon return from a knee injury, although probably not this week. He continues to rehab his right knee, which he injured in a victory against Seattle in Week 2.
