Carlton star Zac Williams has been handed a one-match suspension for his hit on St Kilda youngster Hunter Clark during the Blues' AAMI Community Series clash with the Saints on Thursday.

Match Review Officer Michael Christian graded the incident as careless conduct, medium impact and high contact.

The suspension will mean Williams will be rubbed out for Carlton's Round 1 clash against Richmond.

The Blues' season opener was set to be Williams' first official match in the navy blue, where he will now watch from the sidelines and look ahead to Carlton's Round 2 match against Collingwood on Thursday, March 25 to make his debut with the club.

Carlton will have the option to appeal the ban.
