Late Ulster collapse sees them leave France with nothing as Ian Madigan's Bordeaux come out on top
Bordeaux Begles 28 Ulster 13
A disastrous final six minutes from Ulster saw them concede three tries and go from the verge of victory to leaving Bordeaux without even a losing bonus point to their name.
A well worked Andrew Trimble try and two Paddy Jackson penalties saw Ulster clinging on to a four-point lead as the game reached its closing stages.
However, Bordeaux sub prop Sebastien Taofifenua squeezed over to put the home side in front, before a high tackle from Ulster flanker Sean Reidy on scrum-half Baptiste Serin resulted in a penalty try being awarded.
That double blow left Ulster trailing by eight with seconds left, but they were awarded a chance to salvage a losing bonus point when Bordeaux were penalised in their own 22.
However, a quick tap from Paul Marshall was quickly recovered by Blair Connor, who sprinted to the other end of the pitch to seal victory and to leave Ulster's Champions Cup hopes in danger after just one game.
