Carlton have sacked utility Josh Bootsma, saying he breached the AFL code of conduct.
The Blues said Bootsma also breached their code with a series of disciplinary issues.
Carlton added they became aware on Monday that Bootsma had been behaving inappropriately on social media.
The Age reported that the indiscretion involved posting explicit images on Snapchat with a teenage girl, whose mother alerted the club on Monday.
Bootsma, 21, has played 14 AFL games since his 2012 debut and his girlfriend is pregnant and due to deliver any day.
He has not been in the senior team this season and was not given the opportunity to address his teammates.
“The club has attempted to offer Josh numerous forms of welfare and support in recent times, however he has continuously not lived up to the standards expected of a senior listed AFL player,” said Blues football director Andrew McKay.
“This latest issue has left the club with no other choice but to take this course of action.
“Carlton players and staff receive education on both social media policy and (the) AFL code of conduct on a regular basis.”
Carlton also said they would continue to offer Bootsma support.
