NEW YORK (CBSNewYork) — Cleveland Browns quarterback Johnny Manziel says he’s taking “full responsibility” for his actions that led to a stint in rehab.

Manziel spent more than 10 weeks at a drug and alcohol rehabilitation center. He was released last week.

“I would like to thank my family, friends, the Browns organization, my teammates, and Browns fans everywhere, for your patience, understanding, and support during my stay at Caron,” Manziel said in a statement released by the Browns on Friday. “The doctors and staff have been amazing and what I’ve learned in the last couple of months has been tremendous.”

The polarizing 2012 Heisman Trophy winner looked overmatched in five games — two as a starter — for Cleveland in 2014, his rookie season. He was drafted 22nd overall.

It was reported that the franchise had soured on Manziel due to his off-field behavior.

“I owe private apologies to a lot of people that I disappointed but a very public one to the Browns organization and the fans that I let down,” Manziel said. “I take full responsibility for my actions and it’s my intention to work very hard to regain everyone’s trust and respect. I understand that will take time and will only happen through what I do and not what I say.”

He added: “I also understand there’s a lot of curiosity about this but anyone who has a friend or family-member that’s been through things like this knows it’s an ongoing process. I’m going to continue to ask folks to try to respect my privacy as I determine to what degree I am comfortable talking about a subject which I consider very personal. Most of you have been considerate about that and I thank you for it. I look forward to seeing my teammates next week and focusing on football and my desire to be the best possible player, teammate, and man that I can be.”

The Browns’ next series of offseason workouts begin on Monday.
