Marcel Coetzee and Sam Carter have been ruled out of Ulster’s Heineken Champions Cup trip to Gloucester but Billy Burns and Jordi Murphy return for the Round Two fixture.

South African Coetzee, arguably Ulster’s most important player in recent seasons, and Aussie lock Carter, who captained the team in last week’s defeat by Toulouse, both picked up knocks against the French side and are unavailable.
