Connacht 26-21 Ulster
Connacht dealt Ulster's playoff hopes a severe blow by beating them 26-21 in a hard-fought encounter at Galway Sportsgrounds.
The home side started the brighter with fly-half Miah Nikora knocking over an early penalty and showing excellent footwork and pace to step between Robbie Diack and Adam D'Arcy for the opening try.
And, after youngster Paddy Jackson had reduced the arrears with two penalties for Ulster, the hosts came up with a second try. This time captain Gavin Duffy applied the finish in the right-hand corner after centres Henry Fa'afili and Kyle Tonetti had given him the opportunity with some slick handling.
Connacht had missed both of their conversion attempts though and that allowed Ulster to draw level when scrum-half Paul Marshall scored with a snipe from the base of a ruck and Marshall added the extra two points.
And Marshall, who was kicking well, added another penalty late in the first half to give his team a 16-13 lead at the break.
The home side made a fast start to the second half though, just as they had done in the first, and winger Tiernan O'Halloran went over in the corner after John Muldoon had brilliantly offloaded the ball to him out of the back of his hand to create the chance.
Again, they didn't hang on to the lead for too long though as Jackson added a try to his numerous successful kicks after Ruan Pienaar had released him out wide on the left-hand side.
A Nikora penalty wrestled the lead back for Connacht and, after both number fours Michael Swift and Lewis Stevenson were yellow-carded for scrapping on the floor, the game stagnated for ten minutes or so.
And just as the two locks were set to return to the fray, replacement Ali Birch was also sinbinned for Ulster for an infringement in front of his own posts and Nikora comfortably added the three points to stretch the lead to five points.
The hosts held on to secure bragging rights over their local rivals and seriously dent Ulster's hopes of reaching the end of season playoffs.
