ELDIN JAKUPOVIC earned Hull City a precious point with a stoppage time penalty save.
The former Swiss international pulled off a fantastic save to deny Dusan Tadic after Alfred N’Diaye had been adjudged to have fouled Maya Yoshida.
It ensured a dramatic end to a game that had meandered along for most of the afternoon. Kamil Grosicki hit the post with an early free-kick but, otherwise, there was little of attacking note until stoppage time.
After Jakupovic’s save, Hull almost snatched all three points as Oumar Niasse was denied a winner by a block on the line.
The draw means Hull are three points clear of Swansea City, who travel to Manchester United tomorrow lunchtime.
Grosicki’s early free-kick had been the only chance of note in the second half. Southampton did improve after the break but found Hull resolute.
City needed vital blocks from Sam Clucas and Harry Maguire to remain on level terms.
Steven Davis also wasted a good chance following poor play from Andrew Robertson before Andrea Ranocchia had to react quickly to deny Shane Long a shot on goal.
For Hull, Markus Henriksen had a shot deflected behind before Eldin Jakupovic denied Tadic with a point blank save after initially making a mess of an attempted punch from the corner.
Oumar Niasse then made a hash of a great knock-down from Henriksen before the late drama that saw Jakupovic deny Tadic and send the visiting fans home celebrating a potentially vital point.
