Defender Michael McGoldrick is a major doubt for Derry's Ulster SFC preliminary round clash with Armagh on Sunday.

McGoldrick aggravated a rib injury while playing for Bellaghy in a recent club championship game and is unlikely to feature against the Orchard County. Derry manager Damian Cassidy was already planning without Charlie Kielt before learning of McGoldrick's injury, so his defensive options have been greatly reduced.

Dermot McBride and Kevin McGuckin are set to start in the full back line, while other options in this area include Brian Og McAlary and Kevin McCloy.

Midfielder Fergal Doherty and Declan Mullan are expected to recover from hip and hamstring injuries respectively, while former All-Star Enda Mulddon should see action from the bench after battling back from a broken foot.
