KIEREN Jack's impending 200th game has been overshadowed by news of a falling out between the Sydney Swans co-captain and his parents.

Fairfax newspapers have reported that Jack and his younger brother Brandon, also a player at the Swans, are involved in a feud with their rugby league legend father Garry and mother Donna.

Kieren is due to play his 200th game when the Swans clash with Geelong at Simonds Stadium on Friday night, but it seems like the occasion will be soured after Donna Jack took to social media to express her disappointment at being told not to attend the match.

Kieren is a celebrated member of the Swans' playing group after coming off the rookie list to win a club champion award, All Australian selection and a premiership in 2012.

Brandon, in his fourth season at the Swans, has struggled to cement a regular spot in the senior side and has played just 27 games, including none this year.

It was also reported that Brandon asked his father to leave the Swans' locker room at a NEAFL match earlier this season.

Garry Jack is one of the biggest names in rugby league circles after playing over 250 NRL games, as well as representing New South Wales and Australia with distinction.

The Swans declined to comment on the situation when contacted by AFL.com.au other than to say the situation was a private family matter, and they would support Kieren and Brandon in any way they can.
