Derry boss Brian McIver unhappy with referee's decisions

Derry manager Brian McIver criticises the decision to give James Kielt a black card in the second half of the Division One match against Mayo.

Kielt had been playing a starring role in a spirited Derry revival, but had to be replaced.

Boss McIver felt it was a key moment as Mayo went on to win 2-12 to 1-13.
