NICK Riewoldt has given no indication he's concerned about his future in the game, despite advice from retired Brisbane Lion Jonathan Brown to consider his long-term health after another heavy concussion.

Brown retired last year after repeated head knocks he said often left him with symptoms well after the event.

He said on Fox Footy on Monday night the St Kilda skipper should let the dust settle after Saturday's brutal concussion against Adelaide and "consult his family and think about what he wants going forward".

While Riewoldt won't train on Tuesday, nor will he play against West Coast on Saturday, the Saints say he hasn't said anything about how the latest knock – that left him in hospital overnight – has affected his mindset. 

Doc Larkins' injury update for round seven 

"We had a discussion the other morning about how many knocks he's had in the past and yes, he's a big player and he's had a long career," football manager Jamie Cox said on Tuesday. "But really, now we rely heavily on the medical advice.

"There's nothing certainly in what we've seen or anything that the medics have given us to suggest it's a concern.

"Nick himself I know is not thinking that way, so we need now to rely on our medics, and his health and welfare will be No.1.

"When he gets the appropriate medical clearance he'll be back playing."

Riewoldt will be tested early next week to see if he's recovered enough to face the Brisbane Lions at the Gabba in round nine. 

He's now suffered five serious head knocks since 2011.

He was also examined in hospital in round one this year after suffering whiplash when bumped from behind by Greater Western Sydney's Tomas Bugg.

Meanwhile, Jack Lonie will be monitored this week after also suffering concussion against the Crows but the Saints won't take risks with their first-year forward.

Leigh Montagna is a chance to face the Eagles on Saturday after suffering hamstring tightness in the warm-up at Adelaide Oval.

Farren Ray could gain a call-up after gathering 28 disposals in the VFL at the weekend in his first game back from a serious hamstring injury.

However, Jarryn Geary is likely to miss again after the corked thigh he suffered in round four against Carlton flared and kept him from playing in the loss to the Crows.

"It was a strange injury," Cox said.

"He managed to play through for a couple of weeks but then something stirred up and caused him some aggravation.

"He was ruled out the night before Adelaide and hasn't settled well yet so he's probably unlikely but we'll test him … we haven't ruled him out yet."

Seb Ross, who like Ray needed surgery to repair a hamstring tendon injury in March, is slated to play for Sandringham against Box Hill on Sunday. 

But the luckless Sam Gilbert's return from a long-term foot problem has hit another snag, with the defender to miss this week with an unrelated problem.

"He's had a couple of frustrating little niggles," Cox said.

"He won't play this week either, he's had an adductor strain, it's very minor but just annoying for a guy who's had his issues. 

"We're hopeful this is just a little thing and a little hiccup on his way back.

"He should play for Sandringham next week."
