UEFA rugby posts?!

I was puzzled to see this awning around the rugby pitch at the Lensbury this week. Rugby teams often stay there when playing at Twickenham or Harlequins but I have never seen any football played there. I later discovered that all the officials for the match tomorrow are staying there….so maybe they have had some local football teams playing there so that they can practise their refereeing etc? None was playing when I was there. There were also some smallish temporary football goals on the pitch!
