Richmond tall Bigoa Nyuon has signed a one-year contract extension that will see him remain at Punt Road until at least the end of 2023.

Nyuon, or 'Biggie' as he is affectionately nicknamed, took big strides forward in his third season at the Tigers, earning his AFL debut in Round 9.

His height (197cm), leap and speed are assets that enable Nyuon to play a multitude of roles, having been most comfortable as a key defender in 2022.

The rookie-listed Nyuon, who had to forge his mum's signature in order to play his first game of footy in primary school, is viewed as an exciting athlete that can become a capable defender at AFL level.

Richmond General Manager of Football Talent Blair Hartley was complimentary of Nyuon's work ethic and emphasised the importance of a strong pre-season as he looks to break into a strong Richmond side.

"After an interrupted first two seasons at the Club, it was great to see Biggie get the opportunity to play consistently this year," he said.

"Biggie worked hard to earn his AFL debut, and we hope that small taste of senior football can serve as motivation for him this upcoming pre-season and for 2023.

"He has some really exciting traits and we look forward to him continuing to grow as a player in the next 12 months."

Nyuon is the last out-of contract Richmond player to be accounted for as the Tigers turns their focus to the 2022 AFL Draft, after Jack Ross and Maurice Rioli Junior were re-signed and Riley Collier-Dawkins, Jake Aarts, Sydney Stack and Will Martyn weren't offered contracts for 2023.
