The Doncaster free press state:
”And we understand Rovers are set to cancel Crawford’s contract in order for the deal to be done. The manner of his departure means his signing for Bolton does not have to take place before the transfer deadline, though Wanderers are keen to make a raft of signings.”
The 28 year old looks set to join Wanderers on a one year deal after falling out of favour at Donny.
Crawford made 42 appearances for Doncaster last season as they reached the League One play-off semis.
Before that, he played over 200 times for Hamilton in Scotland.
