The Tigers have been bolstered by the re-signings of Daniel Rioli and Nick Vlastuin on the eve of the 2019 season.
The premiership teammates have each signed two-year deals, locking them in at Richmond until the end of 2021.
Rioli said it was an honour to continue on at Punt Road.
"My grandfather played here and I want to play as many games as possible at this Club so I’m rapt to be on board for a couple more years," he said.
"I hope to continue what I’ve brought to the club, and to try and be a leader to the younger boys coming through."
Vlastuin told Richmond's website he couldn't see himself playing anywhere else.
“When the call came through I was really excited, I didn’t want to go anywhere so it’s good to get it done before the season starts,” he said.
