Ahead of taking on Glasgow, Ulster coach Neil Doak admits his side require "a favour" from elsewhere if they are to secure a home PRO12 semi-final.
Ulster are currently one point adrift of pace-setting trio the Ospreys, Glasgow Warriors and Munster with just one fixture to play in the regular campaign.
The Ravenhill outfit travel to Scotstoun Stadium this weekend for their pivotal clash with Glasgow but coach Doak knows that even victory might not be enough to secure a home play-off, with the Ospreys travelling to Connacht while Munster host the Dragons in one of the tightest PRO12 seasons to date.
"Our thought process is about going to Glasgow and getting a result," Doak told PRO12rugby.com.
"Obviously we have to rely on somebody else to do us a favour with Munster and the Ospreys, but we'll be focusing on Glasgow.
"We've got to regroup and make sure that we're ready to go over there and look to get the win.
"To come back and get the draw against Munster showed great character in the squad.
"It was probably a little bit ironic in that we played them earlier in the season and missed a kick to win the game, and we got one here to draw.
"There are four quality sides in the play-offs and I think on the day anybody could beat anybody.
"We have to go to Glasgow now and make sure we shore up on a few areas, try to get another good performance together but hopefully get the result as well."
