NFL suspends Johnny Manziel four games for violating susbstance abuse policy

Manziel's promise of sobriety beginning July 1 may have come a bit too late.

Free agent quarterback Johnny Manziel has been suspended four games of the 2016 season for violating the NFL's substance abuse policy, according to TMZ.

The suspension would not roll over into 2017, according to TMZ, who cited league sources. This means the quarterback wouldn't have to serve the suspension if he isn't on an NFL roster for the first four weeks of the season.

The former Cleveland Browns quarterback, who has had trouble keeping himself together during his professional football career, recently vowed he'd be getting sober beginning July 1. The Texas A&M grad has been under a microscope since he won the Heisman Trophy in 2012.

Manziel was spotted wearing a Browns jersey Tuesday on his way to Cabo San Lucas, Mexico, just before he made his sobriety pledge.
