Cleveland Browns coach Mike Pettine revealed on Wednesday that he believes quarterback Johnny Manziel is in a "better place" since entering rehabilitation treatment earlier this month, the Washington Times reports. 

The announcement has sparked rumors that the player may soon end his time in rehab and resume his contract with the team. 

"He's in a much better place now than when he went in," Pettine said, according to the site. 

"He's very determined to come out of it in a much better way."

Atlanta Falcons offensive coordinator Kyle Shanahan highlighted Johnny Manziel's contributions to the Cleveland Browns during a recent interview, declining to share specifics about his rehab program. 

"Johnny's a great guy, and I think he does get a little bit of a bad rep with that, because Johnny worked very hard for me," Shanahan told ESPN. 

"I really enjoyed coaching him."

Cleveland Browns quarterback Johnny Manziel entered rehabilitation treatment last Wednesday, adviser Brad Beckworth told ESPN on Monday. 

"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 said, according to the site. 

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

Although Manziel nor Beckworth have revealed an official reason for the rehabilitation treatment, rumors have already surfaced claiming that substance abuse may be responsible. The Cleveland Browns quarterback is said to have shown a continuos pattern of lack of dedication to his sport and more interest in nightlife.
