Star Richmond forward Josh Caddy has apologised for on-field comments he made during the Tigers' win over Hawthorn last Thursday night.

On two separate occasions Caddy called Hawks duo James Frawley and Daniel Howe a "spastic", and has now said sorry for using the derogatory term on the field.

“I’d like to apologise for the way I acted during last Thursday night’s game,” Caddy's statement on Instagram began.

“I apologise to both James and Daniel for the remark I made and am deeply remorseful to have offended people in the community.

“The insensitive comments were made in the heat of the moment but that is no excuse and I accept that the language over-stepped the mark, was a terrible look, and is totally unacceptable. For that, I am truly sorry.”
