Wests Tigers coach Ivan Cleary has reportedly donated a kidney to his ill brother Ash.
According to Nine News, the 46-year-old had the operation in Sydney last week and spent several days in hospital after the procedure.
The report said that Cleary has the "full support" of the West Tigers.
Cleary made 186 appearances as a goal-kicking fullback in the NRL before making the transition into coaching, spending six seasons as Warriors coach before joining the Penrith Panthers and later the Tigers.
It has been a big year for the Cleary family, with Ivan's son Nathan playing every single game for the Panthers and finishing the season as the competition's highest points scorer with 228 points.
At 19, he became the youngest player since 1913 to achieve that feat and was the youngest player to reach 200 points.
Nathan ended up playing against his dad's team in round 22 too, the first time in 28 years that a father had coached against his son in the competition. The Panthers won the match 28-14 with Nathan kicking four conversions.
Nathan still lives at home and prior to the encounter between he was quoted as saying "I might not get fed. I don't think I'll be telling him too much. Definitely not about our game plan or anything. A bit of banter might get tossed around here and there."
The Tigers finished back in 14th position.
