Ian Evatt felt Bolton Wanderers attacker Amadou Bakayoko did not deserve a red card for his strong first half challenge against Adam Clayton in the win over Doncaster Rovers.
Wanderers took the lead after the break thanks for Bakayoko slotting home after being found in the box by Jon Dadi Bodvarsson.
The hosts got back on level terms thanks to substitute Mipo Odubeko smashing past James Trafford to give Donny hope.
