ORCHARD PARK, N.Y. — Quarterback Josh Allen trolled Bills fans by wearing a red helmet at the start of last year's Blue and Red practice at Highmark Stadium. He later switched to a white helmet.

Fast forward to Friday evening, when Allen donned a blue helmet as he raced out of the tunnel and onto the field. And, like last year, he switched back to the traditional white helmet.

"Blue helmets are the new red helmets," the Bills said in a social media post as the event got underway, later adding, "It's beautiful."

Many teams across the NFL have announced throwback jerseys and helmets as training camps started to open. The Tennessee Titans, New York Jets, and Philadelphia Eagles are among those who will have clean, classic look during a couple regular season games.

In fact, the Eagles will wear their Kelly green jerseys against the Bills in Week 12.

The Bills have not announced any alternate jersey plans for the upcoming season, at least not yet.
