Neil Doncaster has green lit the governing body to push back the deadline for those last second deals this summer, with the Premier Sports Cup taking centre stage at the end of August. There is packed card of last 16 ties pencilled in for August 31 including Hearts welcoming Kilmarnock and Celtic travelling to Dingwall to face Ross County.
