Richmond's Chris Newman has given up the captaincy of the AFL club.

The tough 30-year-old backman, who will play on next year, announced his decision before the Tigers' last game of the season, against Port Adelaide at the MCG on Sunday.

Midfield star Trent Cotchin will be highly favoured to take the reins, although a successor is yet to be named.

Newman's 214 AFL games do not include a final, with the Tigers not having reached the playoffs since 2001, but he expects his successor to guide the club into a more successful era.

"It's probably something I've been thinking about for a little while. I think it's just the right time," Newman told the Tigers' website.

"I've had the privilege of being captain for four years and I think whoever takes over this role can lead the boys into the success that I think is coming.

"I still pinch myself a bit. To captain an AFL side, let alone the Richmond Football Club, is mind-blowing when I think of it.

"I don't think I'd step away from the role if I didn't think there would be players who could lead the way.

"Whoever that player is, I've got the utmost confidence that they'll do an even better job than I did."
