The news surrounding Graham’s signature broke earlier in the week, although the other two commitments came as a surprise to the Tigers faithful.
Nankervis added an extra year to his contract that will now see him stay in yellow and black until at least the end of the 2020 season, while Grimes’ three-year extension will see him stay a Tiger until 2021.
Graham’s two-year deal will see him remain until the end of the 2020 season.
Richmond’s General Manager of Football, Neil Balme, told the club’s website he was thrilled to get all three signatures for the future.
“It’s pleasing to see that Toby, Dylan and Jack are all invested in the long-term future of the Richmond Football Club,” Balme told richmondfc.com.au.
“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.
“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.
“These signings are a credit to Blair Hartley and the Club’s recruiting and list management staff, who work tirelessly behind the scenes.”
