Dylan Grimes and Toby Nankervis have been rewarded with new Richmond deals after stellar 2017 campaigns.
They are the latest of the Tigers' premiership side to re-commit to the club who have also just secured Jack Graham to an extended deal.
Defender Grimes, who was due to come out of contract at the end of his year, has been locked in until the end of 2021.
Nankervis, three years younger than Grimes at 23, had a year still to run on his existing deal, and has now signed through to the end of 2020.
Grimes had been plagued by injuries for much of his career until last year when he played every game and finished fifth in the best and fairest.
Nankervis lined up in all but one game after managing 12 in three years at Sydney.
Tigers football manager Neil Blame said it was pleasing that the three players had all invested in the long-term future of the club.
"Toby and Jack came to Richmond just over a year ago and seamlessly fitted into the club's culture. They were prepared to work hard from day one and this ultimately showed with their success in 2017," said Balme.
"Dylan has been at Richmond for eight years and has been a dedicated servant of the club over that time. He is a very skilful footballer and a great mentor for our younger players, like Toby and Jack.
"Toby, Dylan and Jack are firmly focused on getting the most out of this pre-season and taking their football to another level in 2018."
Richmond are 1212/1 to win the Grand Final and 1/1000 to finish in the top four.
