Sheffield United have extended keeper Mark Bunn's loan spell from Blackburn Rovers for the remainder of the Championship season. The 25-year-old former Northampton keeper, who has also played with Leicester, has been a regular for Kevin Blackwell's side making 20 league appearances so far.

Bunn is eligible to feature for the South Yorkshire outfit in their FA Cup clash with Championship rivals QPR this weekend after Rovers granted him permission to play.
