Brodie Smith and Will Hamill are making pleasing progress in their recovery from concussion but a decision on their availability for the Round 23 game against North Melbourne will not be made until later this week.

Smith and Hamill were both concussed in the Round 21 loss to Port Adelaide and are currently observing the AFL’s concussion protocol.

“Pleasingly to this point they’ve met all of the milestones associated with that and if that continues to be the case they should be available for selection this weekend but we won’t know about that until later in the week,” Head of Football Adam Kelly said.

Elliott Himmelberg will have a scan on his right hamstring this week but has been ruled out of the Kangaroos clash on Sunday. Himmelberg suffered the injury while diving for the ball in the first quarter against Melbourne at the MCG on Sunday and was subbed out of the game.

“Elliott looked quite promising early in that game so it was disappointing we had to sub him out, he’ll have scans on that hamstring and it’s (extent of the injury) to be determined but it’s looking highly likely he will miss the remainder of the year,” Kelly said.

Ruckman Reilly O’Brien has played his last game for the 2021 season after missing the loss to Melbourne with a knee injury.

O’Brien hyperextended his knee against Port Adelaide and scans revealed a low grade lateral ligament tear. He does not require surgery but will not play against North Melbourne this weekend.

“We’re taking a very conservative approach with Reilly, he’s had a really big year and has obviously carried those ruck duties extremely well throughout so he’ll now focus on his off-season program,” Kelly said.

Defender Luke Brown is making good progress in his rehabilitation from Achilles surgery and is expected to resume running on Tuesday which will put him in the best position to attack the start of pre-season.

“Pleasingly with Luke he’s recovered well from that surgery and today he’s due to be back on ground running for the first time in his program, that’s an important milestone for him and we’re really pleased with the progress that he’s making,” Kelly said.
