Curtis Davies is reportedly due to hold contract talks with Hull City on Monday afternoon, with the Tigers confident of securing a £2.25m swoop for the former England Under-21 international.
Hull boss Steve Bruce has made Davies one of his top transfer targets ahead of a return to the Premier League next season, with Birmingham accepting their improved offer last Friday.
Davies is expected to arrive at the KC Stadium tomorrow afternoon for final talks over a three-year contact with a medical to follow, according to The Mirror.
The 28-year-old has Premier League experience from spells at Aston Villa and West Bromwich Albion, but has spent the last two seasons in the Championship with Birmingham.
