Vito Stellino of the Florida Times-Union is reporting that Jacksonville Jaguars defense end Aaron Kampman will have an MRI on his knee tonight. Kampman tweaked his knee in practice. As of now, the severity is  unknown but an MRI is rather concerning. Losing Kampman for any period of time would be a devastating blow

UPDATE: Tania Ganguli reports that it is Kampman's right knee, not the knee he had reconstructive knee surgery for a torn ACL. That's the good news, so far.
