Richmond has officially re-signed premiership winning trio Toby Nankervis, Dylan Grimes and Jack Graham for the foreseeable future.

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.

โ€œItโ€™s pleasing to see that Toby, Dylan and Jack are all invested in the long-term future of the Richmond Football Club,โ€ Balme told richmondfc.com.au.

โ€œToby and Jack came to Richmond just over a year ago and seamlessly fitted into the Clubโ€™s culture.

โ€œThey were prepared to work hard from day one and this ultimately showed with their success in 2017.

โ€œDylan has been at Richmond for eight years and has been a dedicated servant of the Club over that time.

โ€œHe is a very skilful footballer and a great mentor for our younger players, like Toby and Jack.

โ€œToby, Dylan and Jack are firmly focused on getting the most out of this pre-season and taking their football to another level in 2018.

โ€œThese signings are a credit to Blair Hartley and the Clubโ€™s recruiting and list management staff, who work tirelessly behind the scenes.โ€
