Ulster Head Coach, Neil Doak, has made two changes to the starting XV that lost narrowly to Scarlets at Parc y Scarlets last weekend for tomorrow evening’s Guinness PRO12 clash against Ospreys.
Michael Allen is named on the left wing and replaces Craig Gilroy who is rested for the match.
Andrew Warwick, who signed his first senior contract with the province this week, starts at loosehead with Callum Black selected on the bench.
Ireland centre, Stuart Olding, has recovered from injury and is named on the bench. Sean Reidy and Peter Nelson are also selected as replacements.
Ulster are fourth in the Guinness PRO12, level on points with Ospreys and a point behind leaders Munster.
The province’s next home match is against Connacht on Boxing Day. There is limited availability for the game. Tickets are available via Ticketmaster or the Ulster Rugby website.
The game is live on Sky Sports and on BBC Radio Ulster.
