When eating with Niko, Marty, and Mark the night before a fight, Scott Voss gets pied in the face with a cherry pie. The remnants of the pie are shown in one shot under his nose, then it flips to another shot and is under his nose and on his chin, then flips back and is only under his nose again.
During the final fight scene with Ken Dietrick the end of Round two is crowned by Dietrick throwing a Haymaker into Scott's lower jaw. This knocks out Scott's mouth guard, you see the mouth guard fly out of his mouth, and land on the wire of the octagon, in the next shot you see it still hanging on the wire. Yet Scott has to hazily walk halfway across the octagon to retrieve his mouth guard from the floor.
