Liam Bridcutt will be the only member of Sunderland's first-team squad to leave the club before the emergency loan deadline after completing his move to Leeds.
Bridcutt today rubber-stamped a loan switch to Elland Road until January after Leeds resurrected a move for the 26-year-old, just as it looked as if he was heading to Cardiff City.
But he will not be reunited with Sunderland and ex-Brighton team-mate Will Buckley after the winger's loan switch at Leeds was terminated.
Buckley had started just one game for Leeds after joining them on loan last month, and has returned to Sunderland a month before his switch was due to finish.
However, Sunderland boss Sam Allardyce has confirmed that Bridcutt will be the sole senior player leaving the club before today's 5pm loan deadline.
The only other departures could be members of the Under-21 squad, with Allardyce keen for Sunderland's youngsters to get experience of competitive football.
"Liam Bridcutt will go out today and maybe one or two more," said Allardyce.
"But there'll be at the younger end to get that first-team experience."
Bridcutt has not made a single appearance for Sunderland this season after the Black Cats were keen to offload the £2.5million man during the summer.
Leeds had spent a month trying to sign Bridcutt and eventually beat off competition from Cardiff and Reading to land the Scotland international.
"It's been on and off for the last few weeks now," said Bridcutt.
"I've had a few other options, but from speaking to the manager he's given me the confidence to come here and show what I can do."
