John Muldoon has emerged as a major doubt for Connacht's trip to Munster on St Stephen's Day after he suffered a nasty gash to his knee playing against Gloucester.
Muldoon failed to train in midweek and head coach Eric Elwood is keeping his fingers crossed that his inform back-row might be able to make it back in time to face Munster.
"We are not in too bad shape at the moment, but John has missed some training," said Elwood.
"He picked up a nasty cut to his knee in Gloucester and he's still stitched up. We are keeping our fingers crossed that he might be back in time to face Munster, but it really is a case of waiting to see how he heals over the next few days."
The loss of Muldoon would be a huge blow to Connacht as they already have to plan without veteran flanker Ray Ofisa, who picked up a knee injury that will see him out of action for another few weeks.
