Burton boss Paul Peschisolido is not prepared to allow defender Tony James to leave the club in the January transfer window.
The 32-year-old has attracted the interest of former club Hereford, where he returned for a brief spell on loan earlier this season.
James has struggled for regular action for the Brewers this term, with Nathan Stanton and Darren Moore in place as Peschisolido's first-choice centre-backs.
But with the League Two club facing a hectic schedule in the coming weeks following a raft of recent postponements, the Burton boss knows he needs all of his squad available to call upon.
"We simply have too much on our plate in terms of fixtures between now and the end of the season for me to contemplate letting Tony go," Peschisolido told the Burton Mail.
"Football changes very quickly in terms of personnel because of injuries and suspensions, and I'm sure Tony is going to have to play a lot of football for us.
"I know he's frustrated at not being in the team, but he's going nowhere until the summer. He was player of the year last season and he's still a valuable member of the squad.
"We've got players like Moore and Stanton who are just not going to cut it once we start a long run of Saturday, Tuesday and Saturday games.
"That's why you build a squad and that's why you have good players like Tony James because you know he's capable of stepping in and doing a good job."
Bulls boss Jamie Pitman has confirmed his desire to land James, who still lives in Hereford, but accepts the ball is now in Burton's court.
Pitman said: "Tony is the sort of player we would be interested in. We have shown Burton we have an interest and it's up to them to make a decision."
