Refs strugling with the pace of the modern game?

Today the ref had to be replaced at both the Sligo Leitrim game and the Kildare Wicklow game. The same had to happen last week in Ballybofey.
Is the pace of the modern game leading to more injuries for our refs?

Referees need to spend more time in the gym.
Don't tell Spillane though.
