Richmond aren't expecting Dion Prestia to spend an extended period on the sidelines following the concussion he suffered during Round 15's loss against Geelong.

The 29-year-old was substituted from the game after the first term collision with Cat Tom Stewart, who has been handed a four week ban from the AFL tribunal, and will be forced to watch Richmond's Round 16 clash against the Eagles from the sidelines due to the AFL's concussion protocols.

The Tigers have confirmed that Prestia is well, and that they are confident he will be able to make a return after the designated twelve day break.

"Dion's progressing well. He obviously pulled up not 100 per cent the day after the game, and the doctor has assessed him and he's now going into that 12-day concussion protocol, which is quite progressive," Richmond physical performance manager Peter Burge said.

"We're preparing him for the Gold Coast game next week. He'll move into some lighter exercise during the rest of this week and then progress into some non-contact training early next week.

"By the end of that week, we'll be able to move into that final stage of contact hopefully leading into the Gold Coast game. We feel pretty confident that he'll be right to play in that game in a fortnight."

The Tigers also provided an update on Trent Cotchin, with the former skipper set to spend more time on the sidelines.

Cotchin hasn't featured for Richmond since Round 14 after suffering an injury to his clavicle, with Burge confirming that the 32-year-old won't run back out until at least Round 18 against North Melbourne.

"Trent had a plate put into where the crack was in his clavicle to reinforce it," Burge said.

"Now, there's just a period of time for that to heal and the bone to heal. So, we're really under the surgeon's instructions with this. He's probably going to miss a couple more weeks. As to exactly what his return game will be, we're not too sure at this stage, he certainly isn't playing this week or next week.

"But, he is back doing some non-contact training, he can actually run and move quite well and he feels pretty comfortable. He's actually going to get a good little block of training in and it's really down to the surgeon and our doctor as to when it's safe for him to play again, but it gives us a good opportunity in the meantime to tune him up a bit and get him ready for the final stages of the season."

Kane Lambert and Noah Balta are both unlikely to return this round as they recover from respective hip and hamstring injuries.

The Tigers will host West Coast at the MCG on Sunday afternoon as they prepare to stake their claim on a top eight spot.
