Hawthorn have received an inspirational boost for Sunday's match against Adelaide at Marvel Stadium after captain Ben McEvoy was cleared to return from a fractured neck.

Collingwood forward Jordan De Goey has been named to take on North Melbourne on Saturday despite suffering tightness in his quad at training on Thursday.
Defender Darcy Moore goes out with a knee injury while Jeremy Howe returns from illness.
North Melbourne have made six changes, headlined by the return of captain Jack Ziebell (facial fracture) and ruckman Callum Coleman-Jones.
Bailey Scott, Aiden Bonar and Flynn Perez were also recalled while last week's medical sub Phoenix Spicer has been named in the 22.
