The incident involving Sloane and Fremantle's Blake Acres took place during the opening quarter of Sunday's match between the Crows and Dockers, with the Adelaide skipper's action on Acres being deemed Intentional Conduct, Low Impact and High Contact.
Sloane can accept a one-match ban with an early guilty plea, meaning he will miss his side's Round 2 clash with Collingwood should he accept.
The MRO have judged the incident in question as Careless Conduct, Medium Impact and High Contact, with Rioli able to accept a one-match ban with an early guilty plea.

Earlier in the week, Lion Mitch Robinson was handed a one-match suspension for his bump on Port Adelaide's Xavier Duursma, a penalty Brisbane have opted to challenge.
