Talks continue between Kilmarnock and Celtic over the transfer of left-back Greg Taylor, with a deal expected to be struck before the window closes.
Celtic had a bid for the the Scotland international, 21, rejected during the week but are now close to meeting their Scottish Premiership rivals' valuation.
Manager Neil Lennon said on Friday that he wanted another left-back before the transfer window closes on Monday.
"There are a number of options and Greg would be one of those," he said.
Taylor was absent from the Rugby Park team for Saturday's Scottish Premiership match at St Johnstone on Saturday, having also missed last week's draw with Aberdeen.
Sunderland and Nuremberg had previously made bids, but the English League One side are understood to have ended their interest.
