Sharrif Floyd's playing career is threatened by a nerve issue in his right knee caused by last September's surgery to repair his meniscus, a league source told the Star Tribune.
Floyd, the Vikings' 2013 first-round pick, missed all but one game last season after undergoing arthroscopic surgery on his right knee. Complications from the operation have affected a nerve and the quadriceps in his right leg, which still aren't working properly six months later. He is continuing to rehab with the hope of a full recovery, the source said.
Floyd, 25, is signed for next season under a fifth-year option, which the Vikings exercised last May.
