Drogheda United begin the defence of the Setanta Sports Cup without skipper Declan O'Brien (calf) and fellow striker Glen Fitzpatrick who is suspended.
Defender Jason Gavin (flu) is a doubt but midfielder James Keddy, who scored a cracking winner against Linfield in last year's semi-final at Windsor Park, has been passed fit.
Irish League leaders and reigning champions Linfield, winners of the inaugural cross-border cup in 2005, wait on defender Pat McShane (ankle) and midfielder Michael Gault (groin) while Conor Downey is a doubt having felt ill before Saturday's 3-0 CPL win over Donegal Celtic.
