Gray has a leg injury and is questionable to return to Sunday's game versus the Titans, Armando Salguero of the Miami Herald reports.
Gray sits behind Jordan Cameron and Dion Sims on the Dolphins' tight end depth chart, so if he is forced to miss the rest of the game, it shouldn't affect the overall performance of Miami's offense too much. In any case, Dominique Jones is in line to take Gray's share of snaps if the latter is unable to return to Sunday's game.
