Health issues have again caught up with Graham Lowe who has been forced to quit his chief executive role with Australian Rugby league club Manly.
A series of medical tests convinced Lowe that his body was no longer up to the rigours of running an NRL club.
The 64-year-old, who has had a long battle with coronary issues, vowed to devote his time to his recovery and family.
Lowe was forced to resign as Manly coach in 1992 due to serious heart problems, while a blood clot in his leg almost cost him his life in 1991.
Lowe underwent a double heart bypass in December 2009 after collapsing at Auckland Airport.
