South African Ruan Pienaar returns to the Ulster lineup after last week's 41-17 victory over Castres.

Stephen Ferris's ongoing injury problems keep him out the side with Iain Henderson maintaining his starting place.

Glasgow Warriors have made five changes to their side which faced Northampton Saints.

Winger Tommy Seymour is replaced by Byron McGuigan as he serves a one-week ban for an illegal tackle on Northampton's Vasily Artemyev.

Glasgow Warriors: Hogg, McGuigan, Murchie, Horne, Dunbar, Jackson, Grant, Hall, Cusack, Ryder, Kellock, Strauss, Fusaro, Wilson

Ulster: Payne, Bowe, Cave, Wallace, Trimble, Jackson, Pienaar, Court, Best, Afoa, Muller, Tuohy, Henderson, Henry, Williams
