Carlton coach Brendon Bolton is optimistic Matthew Kreuzer will be able to find a way to bring his heart issues under control.
Kreuzer has been ruled out for the rest of the AFL season after suffering his second heart scare on Saturday.
The 29-year-old first experienced a worrying elevated heart rate during the round 17 loss to St Kilda.
Kreuzer was due to return against the Dockers in Perth on Sunday but was scratched from the side after experiencing another heart scare the day before the game.
The 173-game veteran will visit specialists to try to get to the bottom of the issue.
Kreuzer is contracted for next season and Bolton hopes the issue won't be an ongoing problem for the big man.
"I would like to think not. I think these things can come under control, as we thought it did," Bolton said.
"But you have to go and do the testing to find that out.
"He had a good training block over the last few weeks so we built up to a point where we were going to select him.
"And then on the training run the day before the game, his heart rate elevated for a small period of time.
"We as a club put welfare right at the front. We're in touch with the specialist and the doctor ... they have to do some further testing.
"The next few weeks we'll hopefully know how that's progressing. You can't take any dangers with that sort of thing."
Sunday's 29-point loss to Fremantle means the Blues are almost certain to collect the wooden spoon - their fifth in the past 16 years.
Carlton (2-18) need to beat the Bulldogs and Crows in the final two rounds and rely on Gold Coast dropping their final two games to jump off the bottom.
Bolton, who has led Carlton to just 15 wins in his three seasons in charge, hopes his team's fortunes will change next year.
"We don't like where we are. The ladder doesn't lie and we have an incredible amount of hard work to do," Bolton said.
