Seems like NICK145 was right all along....
I hate bad rumours about Freo... they always seem to be correct
AFL website Late Live Mail:
12:31pm: MICHAEL TO MISS?
"Strong rumours are emerging out of Perth that Fremantle star defender Michael Johnson will miss tonight's preliminary final with a back/hamstring injury.
Fremantle’s emergencies include key defender Alex Silvagni and half-back Clancee Pearce.
Pearce has found himself out of favour over the past eight weeks. He’s played 18 games this season, including the first 11.
Fremantle’s other emergency is ruckman/forward Zac Clarke. Both Clarke and Pearce were dropped for the preliminary final."
