Richmond superstar Dustin Martin has trained away from the main group today as the Tigers prepare for their preliminary final against Collingwood on Friday night.

According to AFL.com.au report Jen Phelan, Martin was kept to light drills away from the team after finishing training early also last week as he tries to recover from a corked thigh suffered in their qualifying final win against Hawthorn.

Defender Nathan Broad also did not participate, running a lap before some doing some stretching on his own.

Despite scares on Friday, stars Kane Lambert and Dan Rioli participated in the session.

Footy analyst David King believes the injury is a little worse than the Tigers are revealing, suggesting it could be a “significant knee issue.”

“I had someone call me on the weekend and just sort of said there’s more to the Dusty story than we’re being told,” King told SEN’s Whateley.

“I think he’s got a significant knee issue, now whether the issue is a management issue, everyone’s got something at this stage, but their fab-four has been pretty much unimpeded the last two to three years really.

“They haven’t missed games of football. You’ve got to keep an eye on this one. It’s a real story.”
