Colts pass rusher Robert Mathis has been told by the league that his new face mask will not be allowed by the NFL. Only a medical clearance will allow any player to wear a mask like the one that Mathis wants.
In the NFL, masks that exceed four horizontal bars and three vertical bars will not be allowed.
Justin Tuck from the Giants and Chris Canty of the Ravens have received medical clearance for their face masks. Mathis has no medical condition that warrants the big mask.
