Johnny Manziel enters rehab, says his adviser

"Johnny Football" will begin the off-season entering treatment to better himself, according to his adviser, Brad Beckworth.

Cleveland Browns quarterback Johnny Manziel, who lost the starting job to Brian Hoyer earlier this season, has a reputation for partying.

"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," Beckworth told

"On behalf of Johnny and his family, we're asking for privacy until he rejoins the team in Cleveland."

Browns general manager Ray Farmer offered his support to the 22-year-old Manziel, whom the team moved up in the 2014 to select the popular pivot with the No. 22 overall pick.

"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 a statement.

"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."

In five games this season, Manziel completed 18 of 35 passes for 175 yards, zero touchdowns and two interceptions. The former Heisman Trophy winner also rushed the ball nine times for 29 yards.

It didn’t take long for the former Texas A&M quarterback to rub some people the wrong way, starting at the NFL draft.

He rubbed his fingers together when he walked on stage, his signature “money” gesture that has endeared him to some fans and annoyed others critical of his reputation.

During a pre-season game, Manziel flipped his middle finger toward the Washington Redskins bench while returning to the huddle in an eventual 24-23 Cleveland loss.
