Middlesbrough have snapped up Swansea City fullback Dwight Tiendalli.
The 29-year-old has only made six appearances for the Premier League side all season, and last played in January.
The Netherlands international is the second arrival at Boro this week after Fernando Amorebieta joined from Fulham on Wednesday, with fellow defender James Husband going the other way.
Middlesbrough are currently third in the Championship, a point off the top.
