The AFL has confirmed its integrity unit will on Monday query Hayden Ballantyne after the Fremantle forward was captured using his mobile phone in the changerooms.

Ballantyne suffered a minor hamstring injury early in the second quarter of the Dockers’ 10-goal thrashing of Richmond on Friday.

He cut a frustrated figure as he went to the Mandurah rooms for treatment, but was then caught by Fox Footy cameras talking on the phone while the match was being played.

Under strict AFL integrity regulations, players are banned from using phones during matches to stamp out the leaking of sensitive information that could be used for betting or other corrupt activities.
