Ten-man Hull claimed a gutsy victory against Watford to ensure they remain outside the relegation zone and in control of their Premier League destiny.
The hosts endured a nightmare first half at the KCOM Stadium, the nadir coming when striker Oumar Niasse was shown a controversial straight red for a challenge on M'Baye Niang in the 25th minute.
Marco Silva's side also saw a decent penalty appeal turned down in the first 45 minutes, but kept their composure in the second period to stun the visitors.
The hosts took the lead when a quick break ended with Kamil Grociski crossing for Lazar Markovic to fire in on the rebound after his header came back off the bar.
