Ulster moved back to the top of the Magners League by winning in Galway despite a late Connacht revival.

The first try came on 32 minutes with Roger Wilson picking up at the back of the scrum to score. David Humphreys got the conversion and added a penalty.

Second-half tries from Isaac Boss and Bryn Cunningham, converted by Humphreys and Paddy Wallace, had Ulster 24-0 up.

But it was Connacht who claimed the bonus point with late tries from Paul Warwick and Matt Mostyn.

Backed by a forceful wind, Ulster dominated possession and territory in the first half but failed to make it pay on the scoreboard.

But then, when Connacht lost number eight Colm Rigney to the sin-bin on the half hour mark for killing the ball, Wilson took a pop pass off the resulting scrum to barge over and score.

Humphreys converted and after Connacht's eighth penalty concession of the half, the former Ireland fly-half arrowed over a late kick for a 10-0 interval lead.

Ulster's second try came again after Connacht had gone down to 14 men - number 10 Mark McHugh was the offender this time for slowing up ball.

Bulky flanker Stephen Ferris made the initial break for Boss' 56th-minute try, with deft hands from Kevin Maggs putting the New Zealand-born scrum-half over in the left corner.

Humphreys' conversion was stunningly accurate, as was Paddy Wallace's after Cunningham, on a long jaunt from full-back, had cut through for Ulster's third try.

By that time Connacht had lost their third player to the sin-bin as replacement Ted Robinson was rightly carded for a spear tackle on Humphreys.

But the westerners' late revival, with both Warwick and full-back Matt Mostyn weaving through for tries, still netted them a bonus point.
