Anthoney Foley will have a scan later today on the shoulder injury he picked up during Munster's epic win at Welford Road yesterday.
Foley was forced off midway through the second-half as he tackled Leicester's Andy Goode and, while the extent of the damage is not yet clear, he faces a race against time to get himself fit for Bourgoin's visit to Thomond Park this weekend.
In Foley's absence, Alan Quinlan, who replaced him yesterday, is likely to start against the French side as the European champions look to build on their outstanding start to the campaign.
Elsewhere, Ulster's joy in the wake of their 30-3 hammering of Toulouse was tempered by the news that Tommy Bowe is facing a lengthy spell on the sidelines having picked up another hamstring injury.
Bowe limped off in the first-half to be replaced by Andrew Maxwell and is almost certainly out of Friday's trip to Llanelli.
