Cleveland Browns quarterback Johnny Manziel has entered rehab for treatment.

Brad Beckworth, friend and advisor to Manziel and his family, confirmed that the rookie 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,” Beckworth said in a statement Monday.

Browns general manager Ray Farmer also released a statement.

“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,” Farmer said.

Manziel started two games this season and completed 18 of 35 passes for 175 yards and added nine rushes for 29 yards. He was placed on injured reserve after injuring his hamstring in Week 16 against the Carolina Panthers.

On Dec. 29, Manziel said reports that his tardiness to a walkthrough for the season finale was caused by late-night partying are “100 percent false.”

Manziel said he went out with friends from his hometown of Kerrville, Texas on the Friday night before the game, but didn’t throw a party.

Manziel admitted he was not at the team’s final walkthrough and treatment sessions at the appropriate time, which led to a fine.

“It’s about action,” Manziel said then. “It’s about being accountable and doing what I’m gonna say instead of looking like a jackass.”
