The courageous forward, who is attempting to overcome a chronic knee injury, wasn’t fit enough to line up for the Cats’ VFL team against Port Melbourne last weekend.
It means the 28-year-old hasn’t had a competitive hit-out since his last senior appearance against Carlton in round five.
Since then the man Thompson has described as Geelong’s “spiritual leader” has been to the United States to see a rehabilitation guru, but the problem is still hampering him.
“I think if he doesn’t play this week, because it’s the end of the VFL season, then he might find it a bit tough,” Thompson said.
“But you never know, if he trains the house down, even when the VFL team stops playing, and there’s a few injuries, then he’s always a chance because of the type of person he is.”
Given Geelong’s VFL team hasn’t qualified for the finals, the club is hoping to organise some practice matches during the coming month so fringe players like ruckmen Mark Blake and Trent West can remain match-fit.
“It would be nice to be able to play some form of football, whether it’s a competitive game, or a shorter game, or a game with less numbers,” Thompson said.
“Some kind of physical hit-out would be great.
“We have to plan thinking that we’re going to go all the way to the last week in September, and that’s five weeks away.
“It would be unfair to play someone [in the grand final] on September 25, who hasn’t played for four games. That’s a long time.
“So we have to try and keep their match-fitness up somehow.”
