**Glasgow Warriors and Ulster will have to quickly blow off the cobwebs when they clash at Scotstoun on Friday night.**\n\nThe Warriors have not played a Guinness PRO14 fixture since January 16 while Ulster’s last match came a week earlier. \n\nThe Irish province are four points behind Leinster at the top of Conference A and, with the Dubliners also in action on Friday at the Dragons, the pressure will be on to not lose any ground. \n\nDanny Wilson’s side need a win to boost their chances of reeling in the top three, currently sitting 12 points adrift of the Ospreys with a game in hand, after their clash with Benetton was postponed due to freezing conditions last weekend. \n\n**The breakdown** \n\nUlster suffered their first defeat of the season last time out, beaten 24-12 at Leinster.
