Trevor Croly's team continue their defence of the all-Ireland title against fellow SSE Airtricity Premier Division outfit Dundalk
Last year's champions Shamrock Rovers are unbeaten in their first six competitive games of the season and convincingly defeated Glentoran by a 5-1 aggregate scoreline in the quarter final. Dundalk, meanwhile, recovered from a poort start to surge into the semi final, beating Coleraine 4-3 on aggregate.
The game, which is a repeat of the 2011 final, is being televised live and Rovers boss Trevor Croly said that he is pleased to be challenging for silverware at this stage of the season.
"It's great to be involved in a semi-final game so early in the season," Croly told the club's official website. "We have done well in this cup in the few years we have been involved, and we’ll be looking to continue that by progressing to May’s final."
David O'Connor remains out of contention for the hosts, while Stephen McPhail and Shane Robinson also miss out. Midfielder Marty Waters is doubtful with a calf injury.
Dundalk will be without Keith Ward and Mark Rossiter for the clash. Richie Towell is a doubt for Stephen Kenny's side, but Simon Kelly is available.
