Youngster Terrell Agyemang has joined Hartlepool United for a second loan spell of the season.
The 21-year-old made four appearances for Pools earlier this season and he rejoins the squad under the new management of Kevin Phillips.
Pools are currently six points adrift of the National League play-off places, but have played more games than any of their rivals.
Agyemang joined Boro last summer from Manchester City.
Fellow youngster Jack Stott is also learning his trade on loan in the National League at high-flying Gateshead, while Bryant Bilongo has made a bright start to life with Ebbsfleet United in the same division.
