Lambert has played 74 games for the Tigers, and was an integral part in Richmond’s premiership.
“We’re always so impressed by Kane, whether it’s his commitment and determination as a player, or his impressive character as a person,” Richmond’s Head of Player Personnel and List Management Blair Hartley told the club’s website.
“He gives us everything each day – we’ve loved watching him develop, continue to take his football to another level, and make others around him better.”
Hartley also spoke about Garthwaite and Coleman-Jones, suggesting the Tigers were thrilled to keep those two around the club for the foreseeable future.
“We’re really pleased with Ryan’s development in his two years with us,” Hartley said.
“Ryan’s a talented player and while we believe he has a long future with us, he’s already shown us he’s capable at AFL level.
“Ryan works incredibly hard and takes every opportunity to learn off his teammates, and we’re really excited to see him progress to play regular AFL games.
“Callum had a great first season with us, we really like his versatility, and look forward to him continuing to develop his game next season and beyond.”
