The ONLY way that KC was allowed to wear those jerseys is with Bells permission.
I can guarantee you that. The first thing a ref will do is either make them switch to white or forfeit the game. Every ref has a checklist of pre game duties and this is one of them.

This is the actual rule.
(e) The visiting team is responsible for avoidance of similarity of colors, but if there is doubt, the referee may require players of the home team to change jerseys.
