A family feud lasting more than 12 months has become public days before Sydney co-captain Kieren Jack plays his 200th AFL match.
Jack's mother Donna posted on Twitter, revealing the Swans star had requested she and husband Garry not attend his milestone match.
It also emerged on Monday that Kieren's younger brother Brandon, also a Swans player, had asked their father to leave the changerooms at a Sydney reserves match.
"@kjack_15 so sad. Dad 200 RL you 200 AFL & you don't want us there, your parents. No appreciation for all the yrs helping you get there," Donna posted.
Garry Jack is a rugby league great, playing more than 200 games for the Balmain Tigers.
He also represented NSW in State Of Origin and played for Australia.
Kieren Jack will reach 200 senior games on Friday night when Geelong host the Swans.
A Swans spokesperson said it was a private family matter and the club was offering support to the two brothers.
It was unclear when Brandon Jack asked his father to leave the Swans reserves rooms at an NEAFL match.
