Andrew Trimble’s focus on Ulster mission

Although obviously initially disappointed at not being included in Ireland’s World Cup squad, Trimble knuckled down to wear the white jersey and he set a record three weeks ago in by-passing Paddy Wallace’s 189 appearances. Now he intends to push on.
Trimble features in an Ulster side showing two changes from the reverse fixture at Murrayfield last Friday with fly-half Ian Humphreys starting for the first time this season and Lewis Stevenson coming in at lock for Dan Tuohy who is sidelined with concussion.
