Hawthorn star Jordan Lewis says the AFL club remains unsure how long captain Luke Hodge will be sidelined.

Hodge suffered a suspected broken arm in an incident where Geelong’s Mitch Duncan was booked for rough conduct in the last quarter of yesterday’s 30-point loss to the Cats.

There is speculation Hodge will be sidelined for a month, adding to Hawthorn’s worrying injury list, but Lewis said on Monday their fingers are crossed it is not that bad.
