If the best defensive player on your favorite NFL team records a quarterback sack this week, you should probably keep your fingers crossed that they don't celebrate with the 'Discount Double Check.'

Somehow, the 'Discount Double Check' has turned into the most dangerous sack celebration in football. Detroit's Stephen Tulloch and Chicago's Lamarr Houston both suffered season-ending ACL injuries this season after doing the 'Discount Double Check' in games this year. 

Tulloch tore his ACL after sacking Aaron Rodgers in Week 3. 

Then there's Houston, who tore his ACL after sacking Patriots backup quarterback Jimmy Garoppolo in Week 8 when the Bears were down 48-23.

The company that 'invented' the Discount Double Check, State Farm, doesn't think there's an ACL epidemic though, they just think that players need to 'celebrate responsibly.'

"It's very unfortunate that these players injured themselves while celebrating, but it is our belief that the Discount Double Check is not inherently dangerous," a State Farm spokeswoman told the Wall Street Journal. "In fact, it can be used to help you save money on insurance when performed correctly. We encourage all athletes to celebrate responsibly."

If you're wondering where the Discount Double Check even came from, it all started in 2012 with Rodgers. State Farm took Rodgers' touchdown celebration where he puts on a title belt and decided to use it in an ad campaign.

In a series of commercials, which you can see below, Rodgers can't believe people are stealing his move. After what's happened so far this NFL season, there will probably be less people stealing his move -- especially after sacks.
