Jackson back as Ulster make six changes

Jackson is one of six changes from the side that thrashed Edinburgh last week while Craig Gilroy is a positional switch when he moves to left wing from full-back allowing Ricky Andrew to wear 15.
All told Ulster have nine Ireland internationals on parade now that Tom Court has returned to tight-head with All Black John Afoa starting at tight-head. With Ulster’s current second-row dearth exacerbated with Lewis Stevenson (knee) and Iain Henderson (hamstring) picking up injuries last week, Belfast Harlequins’ Neil McComb partners Dan Tuohy in the engine room.
