can't see it on the sky coverage, but Wellens was laying 2 meters directly behind the play of the ball when wigan was on a roll and Mcllorum was trying he's best to get to the ball and pushed Thornley out the way in the process. There was no protests from Wellens or any other saints player so cant see it being as malicious as some are trying to refer it as, also no doubt wellens was hurting but there is no way he gets back 70 meters that quick whilst being out of it.
