Johnny Football is in rehab.

Johnny Manziel, the Heisman trophy-winning quarterback who endured a rocky season after being chosen in the first round of last year's NFL draft by the Cleveland Browns, has checked himself into a treatment center, according to a statement from the team.

 "Brad Beckworth, friend and advisor to Manziel and his family, has confirmed that Johnny entered treatment on Wednesday," read the statement. "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," it concluded.

Manziel who was as well known for his partying ways as for his flair for dramatic wins while at Texas A&M, sat on the bench for most of his rookie season, before finally earning a start in the team's second-to-last game, a 30-0 blowout at the hands of the rival Cincinnati Bengals in which Manziel completed just 10 of 18 passes for 80 yards and two interceptions.

But from before training camp throughout the season, several incidents drew attention to the flamboyant 22-year-old's constant carousing. An infamous picture of Manziel swigging from a champagne bottle while floating in a pool on an inflatable swan at a party in Austin, Texas, came out in June. A month later, another picture surfaced of him appearing to roll a bill up in the bathroom of a Las Vegas bar, fueling speculation he could be using drugs.

In a damning story last month that included interviews with several teammates, ESPN reported the Manziel he was routinely late for meetings during the season and failed to study the playbook. He was suspended for the team's finale, after team representatives reportedly had to go find him, only to discover him drunk, a team source told ESPN.

The Browns did not specify what problem Manziel sought help for. Earlier this season, ESPN's Skip Bayless said he'd spoken with several people close to the Browns QB and was convinced Johnny is an alcoholic.

The Browns took Manziel with the 22nd pick in the 2014 NFL draft, and his No. 2 became one of the top-selling jerseys in the league. He hung out with Cleveland Cavaliers superstar LeBron James, and was frequently photgraphed rubbing his fingers together in what he called the "money sign." But on the field, he was a bust. Manziel completed 51.4 percent of his passes in five appearances with zero passing touchdowns and two interceptions. With the free agency of Brian Hoyer, who started most of last season, Manziel is being counted upon by the Browns to take over as signal caller next year barring the addition of another quarterback.

Browns General Manager Ray Farmer issued a statement saying the team is standing behind Manziel.

"We respect Johnny's initiative in this decision and will fully support him throughout this process," said Farmer. "Our players' health and well-being will always be of the utmost importance to the Cleveland Browns."
