Injured Magpie Jordan De Goey has flown to Germany to be treated by world renowned hamstring specialist and Bayern Munich head doctor Hans-Wilhelm Muller-Wohlfahrt.

De Goey suffered a hamstring strain in the first quarter of his side's qualifying final win over Geelong on Friday night and was unable to complete the match.

It was the 23-year old's first game back from the same injury suffered in round 19.

Teammates Ben Reid, Darcy Moore and Jamie Elliott have all been treated by Muller-Wohlfahrt, as well as the likes Ronaldo, Steven Gerrard, Harry Kewell and Usain Bolt.

“Anything that can reasonably assist and expedite Jordy’s recovery is worth exploring,” said Collingwood GM of Football Geoff Walsh told the club website.

It is unknown how long De Goey will be in Germany for, but the Pies are are hoping to get the star forward back for a potential grand final berth.

He has already been ruled out of the club's preliminary final clash Saturday week against either Brisbane or GWS at the MCG.
