Mason Cox will play against the West Coast Eagles, however a possible misunderstanding has plagued the case, according to Fox Sports.

In the build up to the tribunal hearing, suggestions were made within the media, that Richmond's medical report insinuated that the contact made on Grimes left him with either a concussion or similar symptoms to a concussion.

This may have influenced MRO Michael Christian, who made comments to AFL Media on Monday afternoon, claiming the 'high' contract grading was reinforced by the (Richmond) medical report.

Alongside these comments, television footage showed Cox's shoulder making contact with Grimes' head on different camera angles.

Christian continually refereed to the medical report as having an impact on his decision (after his Round 2 findings were released), however due to confidentiality reasons, no medical report details were disclosed.

Richmond's medical report was finally tabled in the hearing, where the club indicated that they had reason to believe Grimes had some concussion symptoms.

Therefore, they conducted a test, with the results actually showing Grimes hadn't suffered a concussion and will not miss any games of football because of the incident.

So who was responsible for this mix up?

Collingwood coach Nathan Buckley revealed on SEN on Wednesday morning there was “nothing in the medical report” around concussion, but added Christian might not have helped the situation.

“I think that there’s Chinese whispers in media, and that’s no good, but I also think that Michael contributed to that in some way by stating the medical report contributed to the finding,” Buckley told SEN’s Whateley.

“That is not a specific statement but it leads to a misjudgment about what Richmond wrote, from what I can gather.”

Speaking on AFL 360, Gerard Whateley claimed that the AFL community had been "misled" in the build up to the Cox hearing.
