Armstrong’s hamstring rules him out of Donegal tie

Michael Armstrong will miss Antrim’s Ulster Championship semi-final against Donegal this Sunday because of a hamstring injury.
Armstrong has been suffering the problem for sometime and was a doubt for their win against Fermanagh.
He did come on as a subsitute in that game but was forced off in the second half.
Apart from Armstrong there are no other injuries to report from the Antrim camp while Donegal are also reporting a clean bill of health ahead of the tie.
