Keith O'Connor is likely to revert from central defence to attack alongside Fergal Coleman with Paul McNally, over a thigh strain, coming in to partner Stuart Byrne at the back.

Winger Sean Prunty has made progress on a dead leg injury but this game may be too soon for him.

Stuart Holt may come into the side to deputise for Perth.

Derry shipped one or two knocks in Tuesday's FAI Cup quarter-final replay win over UCD at the Brandywell with Gary Beckett the chief casualty with a thigh injury.

With Monday's League Cup semi-final against Bohemians at Dalymout Park in mind, Beckett won't be risked.

Padraig Moran can expect to start on the left flank.
