Carlton player Elijah Hollands was left "shattered" following a disappointing performance on Thursday night against Collingwood.
Hollands had just one possession and three pressure acts from 60 per cent game time, with vision circulating on social media where he appeared out-of-sorts.
"He's pretty shattered with his game, to be honest with you," Voss said.
"I spoke to him after the game and he was really disappointed with how he started the game, really upset.
"He sort of feels like he's let me down so I had a good chat with him. He was pretty emotional after the game.
"He didn't play a great game and struggled to get his way into it and feels disappointed with his performance and obviously with the importance of the night, he feels like he's let people down.
"We've got to keep supporting people through those situations."
Hollands spent most of the last quarter on the bench, with Voss indicating it was a result of his quiet night and the Blues needing to find the right mix to try and win the game.
The 23-year-old took personal leave in 2025 and was delisted following the conclusion of last season, before fighting his way back onto Carlton's list in the Supplemental Selection Period (SSP).
Meanwhile, Harry McKay is set to miss Carlton's clash with Fremantle due to a concussion suffered in the last quarter.
The key forward has a history of head knocks, with the Blues undoubtedly set to take a cautious approach with such a key pillar of the side.
