Sharp set for Sheffield United switch
BLADES striker Billy Sharp is expected to complete a £1.15m move to Doncaster Rovers this afternoon as Blackwell remains in the hunt for Sunderland defender Nyron Nosworthy.
Former Blades defender Rob Kozluk is back training with the club after his release by Barnsley and former Tykes and Peterborough United defender Tom Williams is on trial at Bramall Lane.
Blackwell says he does not expect coach Gary Speed to be interested in the vacant manager's job at Swansea City.
