Drogheda United go head-to-head with Bohemians in tonight's eircom League of Ireland Premier Division clash at United Park, kick-off 7.45pm.
United boss Paul Doolin welcomes back Mikko Vilmunen and Simon Webb into his squad but is still missing several senior players who are still out injured.
Bohs will have to plan without John Paul Kelly (ankle) and Jason McGuinness (back) as they miss out through injury again.
On a positive note for the Gypsies, Harpal Singh comes back into contention after recovering from a shoulder injury.
Connor is likely to give the nod to Darren Mansaram and Glen Crowe up front with Neale Fenn dropping to the bench.
"It is not very often that I say a match is a must win game but it is clear that this is one we cannot afford to lose in the race for the title," said Connor.
"A win, on the other hand, will mean that we are genuine title contenders."
