A great week for prop Tom O'Toole has been capped by his inclusion in the Ulster 15 to play Bath in Saturday's Heineken European Champions Cup Pool 3 game.
O'Toole replaces Marty Moore at tight head in the only change to the side that lost to Clermont Auvergne in France last weekend.
O'Toole was one of eight Ulster players named earlier this week in the Ireland squad for the Six Nations Championship.
Will Addison will start the game at full-back having been an injury doubt in recent days.
The match will provide another opportunity for scrum-half John Cooney to impress Ireland coach Andy Farrell ahead of the Six Nations.
Ulster will guarantee themselves a quarter final spot if they win. They are currently second behind Clermont in the Pool.
Kick off at the Kingspan Stadium in Belfast is at 3.15.
The Ulster team in full is:
(15-9) Will Addison, Robert Baloucoune, Luke Marshall, Stuart McCloskey, Jacob Stockdale, Billy Burns, John Cooney.
(1-8) Jack McGrath, Rob Herring, Tom O’Toole, Alan O’Connor, Iain Henderson (Capt.), Sean Reidy, Jordi Murphy, Marcell Coetzee.
Replacements: Adam McBurney, Eric O’Sullivan, Ross Kane, Kieran Treadwell, Nick Timoney, David Shanahan, Bill Johnston, Craig Gilroy.
