Sydney Stack's first season in the AFL was certainly one of the stories of the season, and he's hit the training track hard in preparation for his second campaign in yellow and black.

Stack missed the AFL finals after suffering a syndesmosis injury at VFL level on the eve of September, and only returned for the VFL grand final, missing out on the senior side's success against the Giants a week later.

Since returning to training during pre-season, Richmond defender Dylan Grimes says Stack has been lighting up Punt Road, and is excited to see what he can produce in 2020.

"He's come back absolutely as we could have hoped, really. He hasn't missed a beat, he's running well, and as you'll see tonight, he's training well," Grimes told reporters on Tuesday night before training.

"We know our players are going to return in good nick, regardless where we finish in the season prior or how strict or lax the off-season programs are, we've had players come back in good nick for a long time now.

"'Stacky' is no exception, so it's good to see him meet those targets in his contract and be ready to tackle the year from the right space."

Grimes also touched on the return of Alex Rance, who is almost back into full training after a recent arthroscope on the knee he had reconstructed back in March.

"He's been building now for 12 months for the season to start, so I think he's going to be in terrific condition. Seeing him move around the track, he's moving better than he was before the knee, it seems to me," Grimes said.

Grimes as well is close to full training, but only a minor wrist injury has kept him from that.
