The keeper was six or seven yards from the half line and in the center of the field, and after fighting for the ball turned back toward his goal( I assume to get back in goal) and ran into the the arm of another player ( yes, from KFC) who was heading for the ball that the keeper had just left. It may have looked to you like he hit him under the chin intentionally , but in the motion of running people do pump there arms and that is what I saw. I just thought that he may have aggravated an injury that he sustained during the Ultra Lions game from the day before when he landed on his neck after being upended by one of his own players.
The AR had called KFC offsides already and the play would have stopped, but the center Ref could not look up because of all the activity around the ball.
We did hear from the trainer after the game that he was okay and we are all thankful that he did not sustain a more serious injury.
