Footballer misses first half hour of a match for the most bizarre reason

The Irish cup game between Athlone Town and Sheriff YC produced one of the most 'WTF' moments of the year.

It's nothing to do with anything on the pitch, but rather an incident in the dressing rooms, where one of the Athlone players was stuck for a whole 30 minutes. https://twitter.com/cahill_ashley/status/634802013717557248 How the hell does that happen? Didn't anyone notice he was missing? https://twitter.com/cahill_ashley/status/634810158359662592
