Nathan White a doubt for Connacht’s trip to Ulster

Table-toppers Connacht could be without Irish prop Nathan White for Friday night's Pro12 trip to Ulster after he suffered a concussion in the first half of Saturday's win over Leinster.

The tighthead prop will go through the normal RTP protocols which will give him a six day return period(from Saturday), if he passes all of the required tests.

Outhalf AJ MacGinty will definitely sit out the encounter, he sustained an AC joint (shoulder) injury and will be out of action for at least four weeks.

Pat Lam's team though will be buoyed by the return of second row Ultan Dillane, who missed out on the game against Leinster after picking up an injury on Irish duty. Having recovered well from his shoulder injury the 22-year-old is available for selection this week and will be a major addition to the Connacht pack.

Meanwhile Jake Heenan continues to undergo treatment for his ankle ligament injury sustained in training last week. His progress will be monitored and a decision made on his availability ahead of the team announcement.
