Connacht scrumhalf Frank Murphy has been ruled out of Saturday's Pro 12 match against Leinster after suffering a concussion against Munster at the weekend.

Connacht are, however, hopeful that fullback Gavin Duffy, who was forced to leave the field during the second half at Thomond Park with a shoulder injury, will recover in time for the match.

Ahead of Friday's team announcement, medical staff will continue to monitor the recovery of flanker Jake Heenan. The 21-year-old was forced to sit out his first game of the season last week due to a shoulder injury.

Pat Lam's squad has been boosted by the return from injury of forwards Michael Swift, Sean Henry and Ronan Loughney who all trained yesterday.

Meanwhile, outhalf Craig Ronaldson faces at least another two weeks on the side-lines with a hamstring injury while centre Dave McSharry will be out of action until after the January break with an ankle injury.
