The first quarterback-specific helmet designed to help reduce concussions has been approved for use by the NFL and NFLPA, The Associated Press has learned.

The helmet, manufactured by Vicis, reduces severity of helmet-to-ground impacts, which league data says account for approximately half of quarterback concussions, including the one suffered by Miami’s Tua Tagovailoa last season when his head slammed violently against the turf during a Thursday night game against Cincinnati.

The helmet performed 7% better than the most popular helmet worn by quarterbacks last season, the league said in a memo sent to team executives Thursday.

It’s unknown how many quarterbacks will switch to the new QB-specific helmet. The league and the players’ union share information from the helmet studies with teams so players can make informed decisions on helmet choice. The only other position-specific helmet already approved is the Vicis Zero2-R Trench for offensive and defensive linemen.
