25-year-old Ellison is a 6'2" left-sided midfielder, and is the League 2 side's top scorer this season with 10 goals. He signed on a free transfer in the summer from Stockport, although as well as clocking up 10 goals he has also picked up 10 yellow cards and one red in 29 appearances this season.
Prior to being at Stockport, he was bought by Leicester for £50,000 from Altrincham by then Foxes manager Peter Taylor, who handed him his only appearance in their Premiership defeat at Manchester United in March 2001.
It's reported that Hull City have made a 'substantial' offer for the player, who would appear to be a natural replacement for the injured Stuart Elliott, but Chester aren't looking to sell.
Blues Mad quote Chairman Stephen Vaughan last night: "The bid from Hull was cash plus two players, but quite frankly we are not interested in selling Kevin to anybody, as we see him as one of the cornerstones of our future development.
"We have seen the valuations of other players from our division in recent weeks, when we made offers for Bury's David Nugent and Phil Jevons of Yeovil Town. Quite frankly, we value Kevin far higher than those players, and even if a monumental offer came in for the player, we would still reject it, that's how highly we rate him.
"As I've said many times before, we are building a side here at Chester City and quality players are always in the forefront of our minds and our planning, and Kevin is in that category."
