Some Browns fans are sacking Johnny Manziel for a month -- and maybe longer.

Tired of the quarterback's off-field transgressions, the fans have started a "Johnny Free February" movement on Twitter. Longtime Browns fan Chris McNeil says his 8-year-old daughter came up with the idea after hearing about more bad news involving Manziel.

As of Monday morning, McNeil says 750 people have signed up for his campaign "not to tweet, retweet, or mention Johnny Manziel on Twitter in February or until he is no longer a Cleveland Brown."

The tipping point for many fans was the latest news concerning the quarterback. Manziel is being investigated for a possible assault of his ex-girlfriend in Texas, where police used a helicopter to find him.
