Marcell Coetzee returns for Ulster's Pro14 clash with Glasgow Warriors at Kingspan Stadium on Monday night as one of eight changes to the team that beat Cardiff Blues last week.
Michael Lowry has been retained at full-back, with Matt Faddes and Craig Gilroy joining him in the back three.
Luke Marshall - who returned last week from injury off the bench - will make his first start of the season, pairing with Stewart Moore in midfield. Ian Madigan has been selected at out-half, with John Cooney starting at scrum-half.
Coetzee returns having recovered from an ankle knock and is joined in the back-row by Matty Rea and Sean Reidy.
Sam Carter will lead the Ulster men from the second row and will partner Kieran Treadwell. Jack McGrath comes in to start at loosehead, with John Andrew being given the nod at hooker, and Marty Moore keeping the tighthead starting berth.
Eric O'Sullivan could make his 50th appearance for the province if called upon from the Ulster replacements. He is named alongside Adam McBurney, Gareth Milasinovich, Alan O’Connor and Marcus Rea in the forwards, while David Shanahan, Bill Johnston and Ethan McIlroy offer back line cover.
