Daryl Kavanagh’s away goal, coming after Danny Murphy deflected Mark Quigley’s free-kick into his own net, gives City a slight advantage against a Hoops side who have also flattered to deceive so far in 2013.
City’s defensive anxieties, having dropped seven points due to goals conceded from the 87th minute onwards in the league already, means Rovers are still favourites to progress.
Colin Healy is suspended, while skipper Kevin Murray remains out with a groin injury.
There are doubts over John Dunleavy, Daryl Horgan and Danny Murphy.
Rovers are without defenders Jason McGuinness and Ken Oman, while Foran and Quigley are doubts.
In the other game, Drogheda United make the trip to Sligo with a two-goal lead safely in the bag.
