Jamieson has struggled on the training track this week and although he suggest he is right to go, the Reds may be taking an underdone player into the decider if he is included in the starting line-up.
"Nah, nah, I'm OK - I'm just trying to ease myself back into it (training)," Jamieson said.
"I did formation work after the media left and did attacking and defending."
Jamieson's heel injury has been worrying him since before last week's preliminary final against the Queensland Roar.
"I had an injection and they just numbed the pain in my heel for the (Roar) match," he added.
"After the game they thought I might have been in strife but I was feeling all right and grateful for what the doctors did for me.
"It's just about managing and see how I go."
