RICHMOND is set to announce the first trade of trade week, sending its third-round draft pick to Port Adelaide in exchange for Adam Thomson.

The 22-year-old inside midfielder has spend the past four years at the Power, but has played just 28 games in that time, and only managed seven this year.

Richmond's general manager of football, Craig Cameron, said the deal was almost done, with pick 42 likely to be the price.

"It's progressed a fair way – I think it's just a matter of us sorting it out with Port Adelaide, which I don't think is going to be a sticking point," he said.

"Probably he'll be for our third-round pick."

Ruckmen are the big talking point of the week so far, with West Coast's Mark Seaby looking for more game time and Dean Laidley throwing Kangaroo Hamish McIntosh into the mix, but Cameron said the asking price was looking too high in the current environment.

"I think that the clubs are looking to see if they can get first-round picks for the ruckmen they're trying to trade, and we'd like to hang onto our first selection.

"I don't know if anything will loosen up as the week goes on, but I think it's going to be very difficult for them to move ruckmen for first-round picks.
