Leeds have signed Mustafa Carayol from Middlesbrough, shortly after his Huddersfield loan ended.
Leeds United have clinched their second deal of the transfer window.
The new addition is winger Mustafa Carayol, who joins from Championship promotion chasers Middlesbrough.
Carayol had been on loan previously at Huddersfield Town, a deal which expired earlier this week.
Earlier in the week Leeds had extended Liam Bridcutt's loan from Sunderland until the end of the season.
Carayol, 27, can play on either wing, and could go straight into the side to play Rotherham United at the FA Cup at this weekend.
He provides an alternative to Sam Byram, who could be sold this month with his contract running out, and increases competition for summer signing Jordan Botaka, who has been unable to break through.
This season he has played 15 times on loan at Huddersfield, nine of which have been starts, and scored three goals.
His best campaign in England came in 2013/14 for Middlesbrough, where he scored eight times in 32 appearances.
