Cian Healy is struggling to be fit for Leinster’s RaboDirect PRO12 match against Munster on Saturday in Lansdowne Road, 7pm.
The Ireland prop has an ankle injury.
The loosehead is the latest front row injury concern for coach Matt O’ Connor, with Martin Moore, Jack McGrath and Tadhg Furlong all unlikely to feature.
O’Connor, whose side face Toulon in the Heineken Cup quarter-final on 6 April, said: “He’s not too bad, he’s still a bit sore post-Six Nations...but we’ve got to have an eye on what’s happening next weekend as well.”
