Connacht threw away a 14-point lead to draw 24-all with Cardiff Blues in the PRO12 League at The Sportsground last night.
"We're disappointed with ourselves to let a lead slip like that," reacted Connacht head coach Pat Lam.
"The defence, when we've defended so well in all the other games, to allow them to roll up in our home ground is disappointing. That is what we're all gutted about."
Ireland possibles Robbie Henshaw, Kieron Marmion and Nathan White all crossed for tries as the Westerners looked on-course for their first bonus-point win of the season.
Instead, Cardiff's continuity game troubled the home side for forwards Macauley Cook and Scott Andrews to ground the ball at the posts and Rhys Patchell added both conversions.
It was two long passages of mistake-free rugby that took the wind out of Connacht's sails, the second try from Andrews being deemed good as he placed the ball at the butt of the upright.
Ireland wing Andrew Trimble struck for two tries in Ulster's 30-0 whitewash of Edinburgh at Kingspan Stadium.
Captain Rory Best and bulldozing number eight Nick Williams weighed in with the other two tries, Trimble's last-minute touchdown guaranteeing the bonus-point.
Leaders Ospreys were desperately lucky to escape Parma with a 15-14 win over Zebre and four points which take them clear of Glasgow Warriors at the top. It all came down to a 71st-minute penalty from Sam Davies, two minutes after centre Gonzalo Garcia had put the Italians back in the lead.
