The Blues' summer signing from Blackburn Rovers, who is currently away on international duty with Trinidad and Tobago, has been given permission to speak to interested clubs about a move away from St Andrew's having failed to hold down a regular starting place in manager Steve Bruce's side this season and reports suggest the Australian side are keen on his sgnature.
Yorke has made just 8 starts for Blues so far this season with another 12 appearances coming from the substitutes bench. The 33-year-old striker has bagged just two goals in those games.
