Director of Rugby, Les Kiss, has named his Ulster match day squad for Friday's Guinness PRO12 match against Glasgow Warriors (Scotstoun Stadium, 7.35pm).
There are five changes to the starting team that faced Zebre three weeks ago.
Captain Rob Herring is joined in the front row by Callum Black, who replaces Kyle McCall at loosehead prop and Ricky Lutton is named at tighthead.
Alan O'Connor is among those who utilised the break to return from injury, he replaces Pete Browne in the second row, partnering Franco van der Merwe. Iain Henderson returns to the starting line-up having been out since December with a hamstring injury. He is joined in the backrow by Chris Henry and Nick Williams.
Paddy Jackson will make his 100th appearance for his Province on Friday night and continues his half back partnership with Ruan Pienaar.
Positional switches result in a new-look backline, with Stuart Olding moving from the centre to fullback and Craig Gilroy returning to the right wing.
