The Blades boss wants to keep a fit and stable squad for the battle to try and get promoted to the Premiership. Blackwell has yet to sign anyone and has confirmed that he may wait until January because the current crop of players are good enough to get promotion 'The Blades Way'.
Blackwell has admitted though that he would like to sign at least two or three players before the transfer window closes in August.
The players will be returning to training around the 30th June mark. To find out more important dates visit the Blades Mad calendar by clicking here.
