Rugby: Ulster star injury concern for Lions URC clash as quartet called up

Ulster are sweating on the fitness of Summer signing Juarno Augustus for this weekend's URC clash against Lions in South Africa.

THe former Northampton man suffered an arm injury in the bonus point victory - their third in a row to start the season - over Sharks in Durban last Saturday. In a squad update, Ulster say they'll monitor his fitness during training this week ahead of Saturday's fixture.

Sean Reffell also sustained a shoulder injury in that Sharks win and he'll be unavailable for selection for a number of weeks.

Iain Henderson, Jacob Stockdale, Nick Timoney and Stuart McCloskey have all left the squad to link up with the Ireland team ahead of the upcoming November matches.

Marcus Rea, Ben Carson, Charlie Irvine and Bryn Ward have been added to the squad.
