Earlier,Hawthorn chief executive Stuart Fox said angry outbursts were part of Clarkson's"make-up"and had tarnished the image of the Hawks coach and that of the club.
But the club board will not sanction Clarkson in the wake of the weekend blow-up in which he swore at a teenage junior football umpire.
Clarkson is believed to have told the 19-year-old official to"f--- off"while acting as a runner for his son Matthew's Ormond Blue team during the South Metro Junior Football League's end-of-season lightning carnival.
