It's payback time. That's what a lot of Seattle Sounders FC fans are saying about Saturday's matchup with the Colorado Rapids at CenturyLink Field.

It's the first time they will be able to voice their opposition to Rapids midfielder Brian Mullan's vicious tackle last season of one of the Sounders' best players, Steve Zakuani. The hit left Zakuani with a broken leg as well as muscle and nerve damage from which he's still recovering.

KPLU sports commentator Art Thiel says Sounders fans have a right to be angry and a right to voice that anger on Saturday - but he warns against going too far.
