It was a frame full of drama on and off the baize as referee Colin Humphries, 24 hours after warning O'Sullivan for a hand gesture, was forced to callafoul after Chigwell's finest potted a red when on 60 with the black ball still to be returned to the spot.
So he dribbled the ball and purposely bumped into Woodson, which prompted officials to calla technical foul a play that helped Dallas seal the game in the closing moments.
