I don't think he was knocked out or concussed, he just broke his nose. He obviously wanted to come back on but after about 30 seconds realised he was light-headed or struggling to breathe or something (I dunno, never broken my nose).
His eyes were glazed over and he looked like he was going to be sick. He was concussed, was definitely more than a broken nose. The medical team have rightly been criticised.
