The transverse process is a small bone on the outside of the back vertebrae. According to Archer, Romo may still play on Sunday against the Cardinals.
Romo was injured in Monday's loss to Washington when he was hit in the back with a defender's knee. He did return to the game.
Romo had surgery on his back late last season, but this injury is not related the previous one.
Romo did not practice all week and is officially listed as questionable for Sunday's game. If he is unable to play, Brandon Weeden would get the start.
