No, only 2 spots available which are both used. I suspect that Mate Colina may not be given another year given his back issues.
It’s possible although if it were to happen it would more than likely have been announced alongside Bradtke’s delisting.
The Cat-B rookie list in its current form has been in existence for 10 years. Richmond has not had both spots filled during that time. I suspect that it has more to do with difficulty in actually getting a Cat-B rookie to join than anything related to Mate.
Although I f Charlie Naish falls through the draft as a father/son he may be the Cat-B rookie and would see Colina delisted.
