RICHMOND recruit Chris Yarran remains 'a few' weeks away from joining his new teammates in full training as the club manages his return from a calf injury. 

Yarran's first pre-season at Punt Road Oval has been interrupted by soft tissue injuries and illness, and he was restricted to running at Wednesday's session.

The 25-year-old now appears more likely to be unveiled late in the NAB Challenge, with the Tigers preparing to take a young team to Perth in 14 days for their first pre-season game.

"Chris is settling in really well with the club and his new teammates, but has had some soft tissue injuries over the pre-season," football manager Dan Richardson told afl.com.au. 

"Our fitness staff are managing his program and training loads at the moment, and we hope he joins the main training group in a few weeks."
