Sunderland defender Blair Adams is remaining on-loan at Northampton Town until season's end.
The 20-year-old left-back has started all 14 games since he arrived at Sixfields in early January, helping Aidy Boothroyd's side to rise off the bottom of the Football League to 18th position in the table.
Adams spent the first half of the season on loan at Npower League One side Brentford, making nine appearances and scoring one goal.
