Oumar Niasse stepped off the substitutes' bench to score twice as Hull gave their Premier League survival hopes a major boost with a 2-1 home win against relegation rivals Swansea.
Hull were struggling to make headway in the second period when head coach Marco Silva played a master-stroke by sending on Niasse in the 63rd minute and the Senegalese striker responded with two crucial goals in the space of 11 minutes.
Alfie Mawson ensured a nervous finish for the Tigers when he headed home in stoppage time for Swansea, but Silva's side held on to clinch their third league win under the Portuguese and climb to within one point from safety with 10 games remaining.
Swansea boss Paul Clement will also be sweating on the fitness of his first-choice striker, Fernando Llorente, who was forced off with an injury in the first-half and is now a doubt for the trip to Bournemouth.
