Birmingham City boss Alex McLeish is uncertain if a deal to sign Doncaster Rovers defender Matthew Mills on loan is a 'goer'.
Mills was the subject of a 'substantial' bid from Birmingham on deadline day, with the promotion chasers reported to have offered £1.5million.
Doncaster rejected the bid and stressed the decision was motivated in part by a desire not to be viewed as a selling club.
However, there have been reports that Mills will now move to St Andrews on loan as McLeish looks to add a centre-half to his squad.
"I don't know if it is a goer, but I would be delighted if we can strengthen the position," McLeish told reporters when asked about Mills after the 1-1 draw with Burnley. "Because I'm frustrated at not being able to get a centre-half to help strengthen it.
"It's not a slight on the others in the squad, but I do believe that it is a position that we need to make a little bit stronger.
"I really don't know (about the Mills deal). I do the recommendations and then it is up to the board to do the deals, but I am looking at the right-back situation as well.
"I want to bring in a right-back having lost (Stephen) Kelly and (Stuart) Parnaby is out for four weeks."
