High-scoring draw at Ravenhill
Ulster had to settle for a share of the spoils in a 29-29 draw against Treviso, which means Mark Anscombe's men have won just one of their last four games.
A hat-trick of tries from flanker Dean Budd, a single score from Robert Barbieri and a penalty and three conversions from Alberto Di Bernardo got Treviso the draw, which also saw them register a try bonus only five days after putting Munster to the sword in Italy.
Though they avoided defeat, thanks to tries from Andrew Trimble and Stuart Olding and 19 valuable points from Paddy Jackson, Ulster's slump in form has done considerable damage in their push for a home semi-final.
After leading 20-10 early in the second half, the home side let their lead slip - and their cause was hardly helped by having Iain Henderson and Lewis Stevenson sent to the sin-bin in the first and second halves respectively.
The Italian side sealed the draw in the last move of the game, which could have been a second successive Ravenhill win for them had Di Bernardo landed the difficult conversion.
