Abu Kamara's late equaliser earned Hull City a potentially precious point in their survival bid and kept Coventry City sixth in the Championship despite a dominant display from the Sky Blues at The MKM Stadium.
Matt Grimes had given the visitors a deserved 46th-minute lead when the midfielder's first-time shot from outside the penalty area hit centre-back Charlie Hughes' leg and dribbled past wrong-footed goalkeeper Ivor Pandur.
Forward Kamara replied in equally fortuitous fashion, latching on to fellow substitute Nordin Amrabat's crossfield pass and seeing his curling effort from an angle hit Jay Dasilva and beat Bradley Collins at the goalkeeper's near post.
Among a string of excellent saves, Pandur denied City top scorer Haji Wright three times during the first half before Kasey Palmer spurned two chances from point-blank range for Hull with half-time looming.
Milan van Ewijk had a chance to win it in stoppage time for Coventry but Pandur palmed the right-back's powerful shot around the post.
Hull are now three points above the relegation zone with four games remaining, and Coventry also have a three-point buffer to seventh-placed West Brom.
