Marty Moore will miss the remainder of the season through injury, Ulster have confirmed.
Moore suffered ankle ligament damage in the province's Guinness PRO14 win over Edinburgh last Friday, going off after just ten minutes of the game, and he will visit a specialist to determine the best course of action.
The season-ending injury will see Moore miss the Guinness PRO14 quarter-finals and will dent his chances of making the Ireland squad for the Rugby World Cup later this year.
Meanwhile, Jacob Stockdale will be monitored ahead of the game against Leinster on Saturday, 27 April after picking up a hamstring injury in the win over Edinburgh, which secured a home quarter-final against Connacht on the weekend of May 3-4.
