The Tigers have secured the signing of Jack Hobbs from Championship rivals Leicester City for an undisclosed fee.
Centre back Hobbs is no stranger to Tigers fans having spent the final three months of the 2010/11 season on loan at the KC Stadium.
The 22-year-old former Lincoln and Liverpool player impressed during 13 appearances to earn himself a permanent move and he now looks set to be a regular feature in the Tigers' back line after putting pen to paper on a contract that runs until 2014.
Speaking about joining Nigel Pearson's squad on a permanent basis, Hobbs said: "I'm delighted now that it's all done and I'm finally a Hull City player. I am really looking forward to meeting up with the other lads for pre season and starting a push towards the Premier League.
"My time at the club last season only reinforced for me what a great club Hull City is - the fans, the stadium, the set up here, the manager and the players meant it was great to be a part of last season and I want to be part of it again."
