Robinson undergoes knee surgery

The New York Red Bulls say midfielder Carl Robinson has undergone successful surgery on his injured right knee.

The Red Bulls said Wednesday that the surgery to repair a torn lateral meniscus was performed by Dr. Riley Williams at the Hospital for Special Surgery in New York.

Robinson is expected to miss five to six weeks of action.

Robinson was acquired March 11 from Toronto FC in exchange for a fourth-round selection in the 2011 MLS SuperDraft.

He has played in four regular season games, starting in three.
