Collingwood advises Mason Cox will not participate in the Club’s Round Three match against Richmond on Friday night after sustaining an injury.

 “Mason experienced soreness in his rib area after the game last weekend,” GM of Football Graham Wright said.

 “His injury was initially believed to be a bruised rib, however, after further investigation scans revealed a hematoma in that region.

 “Mason’s health is our priority here – he will now undertake further scans before we determine a timeline for his return.”
