Elijah Hollands has been ruled out of Carlton’s clash with Fremantle next weekend as the midfielder continues to receive support following his mental health episode on Thursday night.

The 23-year-old was credited with just one disposal in the loss to Collingwood despite significant game time, with footage raising concerns for his welfare.

The Blues began looking into the situation immediately after the game with CEO Graham Wright addressing the “unprecedented and complex circumstances” on Sunday.

Wright said Hollands is doing “OK” but the decision has already been made to take him out of the side for Carlton’s trip to Perth to face the Dockers on Saturday night — with no timeline set on his return to the AFL.

“I had some contact with him yesterday, he’s getting great support. He’s with his dad and family and obviously getting support through our medical staff and the medical staff from the AFL,” he said.

Wright confirmed Carlton staff were aware Hollands was struggling during the game but conceded he was still unsure exactly when concerns were first raised.

Asked to explain why the club allowed Hollands to play so many minutes, including after he was benched to start the fourth quarter, he said: “We’re looking into all that right now.”

7NEWS chief football reporter Mitch Cleary believes that remains the “biggest question” to come out of the investigation, which is being handled by Carlton before being handed over to the AFL.

Channel 7 expert Kate McCarthy argued the Blues “failed their duty of care” in putting Hollands back out on the ground.

Wright conceded the Blues are asking themselves if they could have done better by Hollands.

“We’re really determined to get to a better solution for what happened in that game,” he said.

Wright said “at this stage” they do not suspect drugs or alcohol played a role in the situation.

“We’re dealing with a mental health issue right at the moment,” he added.

“But we’re in the process of going through all the circumstances leading up the game, two or three weeks prior to the game — were there changes to Elijah in that regard.

“And then we’re working through what happened in the game, post-game.”

Hollands twice took personal leave from Carlton last year, later revealing he had been battling with his mental health and issues with alcohol.

The former Gold Coast player was delisted by the Blues at the end of last season despite having a year to run on his contract.

But Hollands was invited to Carlton training over summer, impressing enough to win his spot back on the list.

He has played all six games this season, averaging 18.4 possessions before his troubled night against the Magpies.

The AFL has requested answers from Carlton once the club works out what happened.

The AFL Players Association was concerned by how the situation evolved and has been in contact with the AFL and Hollands’ manager to better understand what happened.

“We are determined to ensure a considered process not just an understanding of what happened but to ensure key learnings come from this, not just for us, but for the broader football community and industry,” Wright said.

Meanwhile, Wright also addressed the circumstances behind Lucas Camporeale’s lacerated kidney in a VFL clash on Friday night.

Camporeale, the son of club great Scott, was in clear pain after a collision in the second quarter but played out the game following an assessment at half-time.

He is now expected to be in hospital for several days.

“He wanted to continue playing in the game,” Wright said.

“The doctors felt that they were confident that he could keep playing.

“He actually played out the game and played quite well to be honest, and then post-game the decision was made to send him to hospital and that’s how that transpired.”
