The Titans look set to have running back DeMarco Murray in the lineup against San Diego this weekend, but things are a bit iffier with another key member of their offense.

Tight end Delanie Walker injured his groin in practice on Thursday and sat out Friday’s practice altogether before getting listed as questionable to play against the Chargers. Walker said Friday that “it’s an injury I can probably play with,” but he will be a game-time decision after a flight to California that will require some extra attention to Walker’s condition.
