**A last-gasp try from replacement winger Peter Sullivan gave Connacht a dramatic 26-24 victory over Ulster at the Kingspan in the Guinness PRO14 Rainbow Cup’s opening round.** Using the captain’s challenge law introduced for this competition, Connacht, with their bench making a crucial impact, came back from what seemed certain defeat to work the winning score with the clock in red. That was after Ulster appeared to have secured the spoils for themselves with a late Dave Shanahan try in this hard-fought Irish derby. It was only the second time that Connacht have won in Belfast since 1960 and will have given a strong Ulster side, who had Iain Henderson back as well as long-term absentee Will Addison, a wake-up call ahead of next weekend’s Challenge Cup semi-final at Leicester. Scrum-half Caolin Blade scored twice in an eye-catching display from the Connacht number nine while, for Ulster, the return of Addison after over a year out also saw him look sharp.
