Cat Duncan on the mend after Mummy clash

Geelong midfielder Mitch Duncan is recovering well after being knocked out in the Cats' surprise loss to Greater Western Sydney and should be fit to play Brisbane this weekend.

Duncan left the field dazed in the third quarter at Manuka Oval in Canberra after coming off second-best in a bone-jarring collision with Giants ruckman Shane Mumford.

Coach Chris Scott said on Wednesday that Duncan, Daniel Menzel, Nakia Cockatoo and upgraded rookie defender Tom Ruggles were all in the selection mix for Sunday's clash against the Lions at Simonds Stadium.
