The West Australian is reporting that Yarran will be selected in the Swan Districts’ reserves side ahead of their clash with East Fremantle in the WAFL on Saturday.
The move has been cleared by the Tigers, with only the AFL now left to approve the deal before Yarran can feature.
Yarran was released from his Richmond contract in November to deal with a mental health issue, and didn’t play a game the club.
The 26-year-old signed a three year deal at the Tigers after being traded to Richmond for pick 19 at the end of the 2015 season.
Yarran played 119 AFL games for Carlton between 2009 and 2015 after being taken with the sixth overall pick in the 2008 national draft.
