Cleveland Browns wide receiver Odell Beckham Jr. was forced to temporarily leave his team's Monday Night Football game against the host New York Jets after officials spotted him wearing a gold-colored helmet shield, according to Browns Radio Network (h/t Nate Ulrich of the Akron Beacon Journal).
Per the NFL rulebook (h/t ESPN's Kevin Seifert in an August 27 piece), "tinted eye shields may be worn only after the league office is supplied with appropriate medical documentation and approval is subsequently granted."
The Oakley Prizm Clear shield, which has a slight tint, was granted an exception after the NFL and Oakley struck a four-year sponsorship deal.
