Celtic are chasing a deadline busting loan move for Cameron Carter-Vickers, according to reports.
Tottenham are keen to offload the defender and he could yet move to Parkhead with the deadline looming at midnight.
Record Sport told earlier on Tuesday how the door had closed on the USA international moving to Glasgow.
It's believed Spurs were only interested in a permanent deal for the 23-year-old, hence why it appeared dead in the water.
But with no takers, a loan has become a possibility late on Tuesday night.
Both Sky Sports and Football London report the two clubs are working to get an agreement over the line before time runs out.
The deal is "being worked on" with the minutes ticking down to the end of the window.
Celtic have already announced deals for Giorgos Giakoumakis from VVV Venlo and Benfica winger Jota, who joins on-loan.
Going the other way, Leigh Griffiths has gone on-loan to Dundee while Odsonne Edouard and Ryan Christie have joined Crystal Palace and Bournemouth, respectively.
