Charlton Athletic have been urged to increase their offer for Hull defender Wayne Brown.
The Addicks spoke to Brown about a potential move earlier this month but talks over a deal stalled.
Brown, 31, is out of the first-team picture at the KC Stadium and had a loan spell at Preston earlier in the season.
Hull boss Phil Brown said: "We have put a price tag on Wayne Brown and Charlton, as yet, haven't come up to that valuation. Until we cross that bridge Wayne Brown will remain a Hull City player."
