Glasgow shock Ulster late on
James Eddie scored a converted try with the last move of the game as Glasgow sealed a rare 13-12 victory over Ulster at Ravenhill.
The home side, who were condemned to their second straight RaboDirect Pro12 defeat, wasted a glorious opportunity to seal a game which they led 12-6 at half-time.
Gregor Townsend's men came back to snatch the four points to remain unbeaten after two games, while Ulster had only a losing bonus point to console themselves with.
With Glasgow prop Moray Low sin-binned late on anything other than an Ulster win seemed inconceivable, but the home side paid the price for missing a host of try-scoring opportunities.
Stuart Hogg, playing his first game since the British and Irish Lions tour, opened the scoring for the Warriors in the fifth minute with a penalty, but Ulster hit back when Paddy Jackson replied in kind two minutes later.
Jackson then landed his second three-pointer after some great offloading from Roger Wilson and Nick Williams, and a long-range effort after the 20-minute mark made it 9-3.
Hogg closed the gap after Ulster strayed offside four minutes before the half hour, but Jackson's fourth penalty sailed between the posts to take the home side's lead to 12-6 at the break.
Ulster upped their tempo in the second half but neither side was able to score, with the home team seeing three scoring chances go begging.
Michael Allen, Luke Marshall and David McIlwaine all had chances to cross for Ulster with the latter actually getting over the line but being held up by a combination of Jonny Gray and Tommy Seymour.
Ulster also failed to put any points on the board from the tee with Jackson's 67th-minute penalty sailing wide. They continued to dominate possession and territory, however, with Low's sin-binning ensuring the Warriors had to dig even deeper to not concede any further points.
Even down to 14 men, though, the visitors resisted and even had a five-metre scrum in the latter stages only to concede a penalty and allow Ulster to relieve the pressure.
They were not finished and after DTH van der Merwe was hauled down by Iain Henderson, the Warriors stayed in the Ulster 22 and from a tap penalty, substitute Eddie crashed over with Hogg's conversion sealing the most unlikely of wins.
