Jacob Townsend has moved to Richmond, with the Tigers trading their fourth-round pick to secure the Greater Western Sydney midfielder.

The Tigers and Giants met on Friday at AFL House to finalise the trade, which has gone through for the current pick No.70.

Richmond also receives the Giants' pick No.120 as part of the deal.

He joins the Tigers on a two-year contract, having been staved of consistent senior chances at the Giants.

"He's obviously missed some opportunities as a lot of young players at GWS have over the last few years," Richmond football manager Dan Richardson said.

"We think he can add something to us and help our midfield out."

The 22-year-old has played 28 AFL games but just one this year, with a foot injury taking a chunk of his season away before he resumed in the NEAFL in round nine.

He didn't get a chance to play at AFL level until the Giants' final home-and-away game, where he had 22 touches against Melbourne. 

The Tigers have had success in recruiting inside midfielders from the Giants in recent seasons, with Anthony Miles now one of their most dependable assets.

Meanwhile, the Tigers continue to talk to Carlton about Chris Yarran and believe they'll secure a trade for the Blues' half-back early next week.

"It's still progressing – we're very confident Chris will be at the club next year," Richardson said.

"We're still working through the best way to achieve that for both parties.

"It's more about some other options we've got to secure a first-round pick.

"We understand Carlton's position of wanting a first-round pick for Chris, it's not as if we disagree with that, there's just a few other things at play but they'll play out over the weekend and I'm sure that will be solved early next week."

Richardson confirmed key position player David Astbury was currently undergoing a medical at the Brisbane Lions after a season where he also struggled for senior chances.

While there is yet to be movement on an official offer, the contracted 24-year-old is expected to inform the Tigers next week of what he wants to do next.

"He's got a tough decision to make in regards to that," Richardson said.

"Dave's a really valued member of our group and a great teammate and key position player but that's the balances we've seen with the player movement today – players who are under contract like Dave is are often looking at their options.

"We respect that and I'm sure Dave will come to us next week with a position from his perspective and then we'll work out what's best for us." 

Astbury finally had a consistent run with his body in the second half of the season after a few years ruined by knee injuries, but failed to break into the senior side.

He was one of the Tigers' most improved players early in 2014 before a second knee dislocation all but ended his season in round nine.

Richardson conceded it would be disappointing to lose him given he was finally fit but understood if we wanted to look elsewhere.
