The NFL has been hit by a rash of nicotine-related injuries this season, as players and coaches are being charged with violations of the league’s concussion protocol.
A report from the Pro Football Talk blog said the league has been using nicotine-based head-pressure pills since 2012.
The report added that in the past, the NFL’s use of nicotine was limited to a handful of players, but that this year it has grown exponentially.
While there is no definitive way to determine the number of players with nicotine-induced head-rushing, ESPN’s report said the Steelers, Bengals, Browns and Bills all have at least 10 players.
According to the report, Steelers players are charged with a violation of the concussion protocol for the second time this season.
Bengals players are facing a charge of a violation for the first time in their career.
The Bengals are facing charges of a second violation for head-surfing, while the Browns and Raiders are facing violations for the third and fourth time.
