Goalkeeper Harry Fisk, defenders Jake Leake and Tom Nixon, midfielders Harry Lovick and Oliver Green and attackers Will Jarvis and McCauley Snelgrove have all extended their stay at the club by a year, with the Tigers holding the option of an extra 12 months.
All seven players have enjoyed loan spells away with lower league clubs, while full-back Nixon captained the Under-23s last season and Jarvis made his senior debut against Wigan Athletic in the Carabao Cup last season, before featuring in their Championship clash with Derby County a week later.
