[Kansas City.com] Chiefs linebacker Keyaron Fox crumpled to the ground without contact on a play in the second quarter Sunday, injuring his right knee. Vermeil said Fox will have a second opinion on the knee, not for a diagnosis but to decide whether he’ll have surgery.

Vermeil said he didn’t want to get into medical terms on Fox because “I’d probably screw it up.” When asked whether tests revealed a possible tear, Vermeil said, “Yes.”
