League leaders Sligo will look to steal a march on their rivals when they welcome Dundalk to the Showgrounds in a re-arranged game on Tuesday night kick-off 7.45pm.

Sligo Rovers will be without Iarfhlaith Davoren and Raffaele Cretaro who miss out through suspension however Richie Ryan returns is back after a ban of his own while Jason McGuinness and Eoin Doyle have recovered from injury.
Dundalk meanwhile have been boosted by the return of 21-goal Mark Quigley and experienced central midfielder Dean Bennett from suspension.
However, 33-year-old striker Jason Byrne is suspended while Carl McHugh misses out as he is away with the Republic of Ireland U19 squad in Bulgaria.
Foster must also make do without long-term injury victims, left-back Eoghan Osborne (fractured tibia), central midfielder Stephen Maher (fractured metatarsal) and centre-half Colin Hawkins (knee).
In their three previous meetings this term, Dundalk and Sligo shared the spoils in both encounters at Oriel Park, with two 1-1 draws, Jason Byrne and Gavin Peers exchanging first-half goals in April before Raffaele Cretaro and Quigley did likewise in late drama in August. In the game at the Showgrounds, in May, Alan Kirby struck early in the second half to give Sligo a 1-0 win.
Dundalk’s last win over Paul Cook’s side came in May last year when Fahrudin Kuduzovic struck the only goal at Oriel Park.
