RICHMOND midfielder Dustin Martin has shut down questions about his future as free agency looms for the star Tiger. 

He walked away from a Wednesday morning media conference, leaving his long-time mentor Mark Williams to talk about whether Martin would stay at Richmond beyond this season. 

Martin becomes eligible for restricted free agency at the end of this year and the Tigers are understood to have put a long-term offer to the quietly-spoken star. 

"That's just between (manager) Ralph (Carr) and the club to sort out … I'm here to talk about the Sherrin today," Martin told reporters at the launch of two new Sherrin footballs. 

When pressed further about his contract, the 25-year-old declined to answer, leaving Williams to step in. 

"I'm sure Dustin will make the right decision," Williams said on Wednesday morning at the MCG. 

"He's very much a loyal man. He loves Richmond, he loves the players there and in time he'll make the right decision."
