Leinster head coach Matt O'Connor has admitted that he has some concerns over his front row players ahead of Saturday's Pro-12 derby against Munster.

Jack McGrath remains the main injury problem for the province because of a shoulder injury but the likes of Cian Healy, Marty Moore and Tadhg Furlong are also struggling to be fully fit.

Healy, who has endured ankle problems all season, is likely to be available if necessary.

But O'Connor has admitted that he would prefer to have the loosehead prop fully fit for next week's Heineken Cup quarter-final away to Toulon.

He said that Leinster would assess Healy "closer to the game."
