Townsend still has a chance to find another club as a delisted free agent, although if no other side picks him up, he will remain a Tiger in 2019.
“We would love for Jacob to remain at Richmond and he knows there is a spot for him at the Club,” Richmond’s General Manager – Football Neil Balme told richmondfc.com.au.
“He is well within his rights as a delisted free agent to look for new opportunities and should they arise, we will support his decision.”
Chol played one match for Richmond, while Drummond played five matches across four seasons.
“Mabior has shown promising signs over the past three seasons and the Club will consider its options over the coming weeks,” Balme added.
“I really feel for Nathan, he has had a rotten run with injuries.
“He has suffered two serious knee injuries since joining the AFL system and has struggled to consistently play football.
“He has always held his head high and been the ultimate professional, even when he was going through tough patches.
“This was a difficult decision for the Club to make. We have no doubt Nathan will forge a successful career in whichever path he decides to take.”
