Cleveland Browns quarterback Johnny Manziel entered treatment on Wednesday with the goal of being a "better family member, friend and teammate," according to his publicist who released a statement via Mary Kay Cabot of the Cleveland Plain Dealer.

The nature of Manziel's treatment hasn't been specified, although the decision to enter treatment was not related to the quarterback's life on the football field. The full statement from Manziel's publicist, Denise Michaels, was tweeted by Cabot on Monday morning:

"Brad Beckworth, friend and advisor to Manziel and his family, has confirmed that Johnny entered treatment on Wednesday. Johnny knows there are areas in which he needs to improve in order to be a better family member, friend and teammate and he thought the off-season was the right time to take this step. On behalf of Johnny and his family, we're asking for privacy until he rejoins the team in Cleveland."

Browns general manager Ray Farmer also released a statement promising support for Manziel, via Jeremy Fowler of ESPN:

"We respect Johnny's initiative in this decision and will fully support him throughout this process. Our players' health and well-being will always be of the utmost importance to the Cleveland Browns. We continually strive to create a supportive environment and provide the appropriate resources, with our foremost focus being on the individual and not just the football player. Johnny's privacy will be respected by us during this very important period and we hope that others will do the same."

SB Nation presents: Final thoughts on the 2014-15 NFL season

Manziel, 22, has developed a reputation for his partying lifestyle since winning the Heisman Trophy following his freshman season at Texas A&M in 2012. He was selected in the first round of the 2014 NFL Draft, but finished his rookie season without a touchdown pass and two interceptions.

In December, ESPN analyst Skip Bayless earned criticism for calling Manziel an alcoholic and a liar, while the rookie admitted that he has to "stop acting like a jackass."
