Tennessee Titans tight end Delanie Walker suffered a broken ankle and ligament damage on Sunday and is not expected to play again in 2018, a source told ESPN's Adam Schefter.
Walker was taken off the field with an air cast on his right leg. He went down awkwardly as he was tackled by Dolphins safety T.J. McDonald in the fourth quarter. The training staff sent a cart to him immediately.
The trainers put a towel over Walker's head as they fitted him with an air cast before lifting him onto the cart and taking him into the locker room.
