BEREA, Ohio -- Johnny Manziel knows he's been a distraction this season and again promises to change his behavior.

The Browns' rookie quarterback was fined for missing medical treatment Saturday. He said he overslept and spent Sunday's season finale in the locker room in Baltimore instead of on the sideline.

Manziel apologized to his teammates for not taking his job more seriously and said "I'm either going to learn or I'm going to be finding something else to do."

Last week, Manziel promised to change his ways only to find himself in another controversy. Asked what he can do to change the perception about him, Manziel said "it's about actions, it's about being accountable and doing what I'm going to say instead of looking like a jackass."

Manziel started two games this season after replacing veteran Brian Hoyer.
