Hull bring in Ince
Former Liverpool man Ince had previously been at Blackpool but spent the second half of last season on loan in the Premier League with Crystal Palace.
With 22-year-old Ince out of contract at Bloomfield Road, he had been linked with a move to Serie A club Inter - where his father Paul played for two years.
However, he has now moved to the KC Stadium on a two-year contract - following Robert Snodgrass and Jake Livermore to the club - with Hull also confirming negotiations over a fee will continue due to the player's age.
"Due to the player’s age, negotiations between the Tigers and Ince's former club Blackpool over a compensation fee continue," they stated on their official website.
"Should the two clubs fail to come to an agreement, the fee will be determined by a tribunal."
Ince, a former England under-21 international, originally caught the eye with his performances in the 2012-13 campaign where he scored 18 goals in the second tier before adding a further seven in the first half of the 2013-14 campaign.
That encouraged Palace manager Tony Pulis to sign him on loan, although he scored just once in eight starts at Selhurst Park.
