Richmond, Hawthorn pay tribute to Shane Tuck
Tuck played 173 games for Richmond before retiring in 2013 and was awarded life membership of the club.
Other clubs also paid tribute to the former Tigers star, many taking to social media to express their shock.
Richmond spearhead and former teammate Jack Riewoldt described Tuck as an inspiring character.
“You always walked taller when you had Shane Tuck playing next to you,” Riewoldt said on SEN radio.
“There are plenty of stories about Tucky and a lot of funny ones.
“He was one of those players that you loved to spend time with because there would always be a story come out of that.”
Former Richmond coach Terry Wallace was at the helm of the Tigers for 99 matches from 2005-09, and midfielder Tuck was the only player to feature in all of them.
“He was just a very lovable person and one of the great characters around that football club at the time,” Wallace told SEN.
“He was not the best player you've ever seen but he was the epitome of honesty and the epitome of what people should love about their footy clubs.”
Richmond will pay tribute to Tuck by wearing black armbands during Friday night's match against Greater Western Sydney.
Tuck and father Michael sit third on the list of most AFL/VFL games played by a father and son combination, with 599 between them.
Michael Tuck was the former individual games record holder with 426 appearances for Hawthorn.
