Gallen timed it, he was expecting 10 in the bin, a few mins either side of half time.
He wanted the QLD cheap shot merchant to get some of his own back, and seriously for those say it had no effect on Miles, you must be watching too many Rocky movies and know nothing.
Gallen hit him with a light left jab, a miss-hit right cross, then followed with a right uppercut when a huddle formed. Myles' legs were jelly at this point. Even the moving .gif earlier in this thread shows Myles eyes glassy after the 2nd hit.
You don't get weeks off for landing punches when squaring up, and Gallen will get a week for the swinging arm.
