Richmond’s Physical Performance Manager Luke Meehan provides the latest injury update ahead of next Friday's match simulation against North Melbourne.

Jason Castagna, hamstring

"Unfortunately, Jason suffered a pretty decent medium-term hamstring injury. It was only two minutes to go in the (match simulation). He's commenced his rehab program already, and we're expecting him to be missing for the medium-term and hoping for him to be available around about Round 1."

Nathan Broad, hamstring

"Late last week, Nathan also suffered a more minor issue with his hamstring. We're hoping that he'll be available for the Melbourne practice game, but he should be okay for the start of the season."

Kaleb Smith, foot

"Kaleb's been in a boot now for three weeks. He has about one more week in the boot and after that we'll know a little bit more and see how he is progressing, he's going well though."

Josh Gibcus, hamstring

"Surgery went really well, it's about three-and-a-half weeks since the surgery. He's already progressed with his running and strength program, everything is going to plan at the moment, it's going really well."

Tom Lynch, plantar fasciitis

"Tom's had a really good block since Christmas. He's, just actually the other day, started some light drills with the team. He's got a lot of work to, we're hoping for him to be available at the start of the season."

Jack Graham, toe

"Jack's trending in a similar trajectory to Tom. He started with the group on Monday and we'll keep building him and have him available for the start of the season."
