HAWTHORN coach Alastair Clarkson says "only time will tell" if the penny has dropped for midfielder Jordan Lewis with regard to his disciplinary indiscretions.

Lewis missed the first two weeks of the season due to a suspension coming out of the Hawks' loss to North Melbourne in last year's first semi-final.

When he returned against the Roos in round three, Lewis was again suspended after being reported for striking Daniel Pratt.
 
Clarkson said the leadership group had spoken to the 21-year-old about his behaviour and he now knows he is of more use to the team when he is on the field "instead of sitting in the grandstand".

Meanwhile, Clarkson says the inclusion of Jamie Charman will have a big impact on Saturday night's match between Hawthorn and the Lions, as he rates the ruckman as one of the best in the competition.

More to come.
