Ryan Giles has returned to Middlesbrough for a second spell on loan from fellow Championship side Hull City.
Left-back Giles, 24, played for Boro in 2022-23, where he claimed 12 assists in 48 appearances as they reached the play-offs.
He left Wolves to move to Premier League newcomers Luton Town but only played 14 times before he headed up to Hull, firstly on loan before that became permanent last summer.
However, he is now linking up again with Boro head coach Michael Carrick for the rest of this season.
Middlesbrough sit fifth in the table, ahead of their trip to Preston North End on Saturday.
