Johnny Manziel enters rehab to 'improve' self

Browns quarterback Johnny Manziel entered treatment on Wednesday, ESPN reports.

"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 offseason was the right time to take this step," adviser Brad Beckworth told ESPN.com through a Manziel spokesman. "On behalf of Johnny and his family, we're asking for privacy until he rejoins the team in Cleveland."

Browns general manager Ray Farmer issued a statement supporting Manziel's decision:

"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," Farmer said in the statement released to ESPN. "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."
