Manziel, who suffered a season-ending hamstring injury last weekend, wasn't required to participate in the Browns' walkthrough ahead of Sunday's season finale against the Baltimore Ravens. Wide receiver Josh Gordon was suspended for reportedly missing the walkthrough.
Manziel had a largely uneventful rookie season until he replaced Brian Hoyer at quarterback in the Browns' Week 13 loss to the Buffalo Bills. His first NFL start came in Week 15 against the Cincinnati Bengals, a 30-0 loss. Manziel started again in Week 16 against the Carolina Panthers before suffering the hamstring injury.
Earlier this week, Manziel told reporters in Cleveland he's spent the year "growing up."
''I'm not the guy that I've always been,'' he said. ''I'm not the Johnny Manziel that came in here a year ago. It's been a year of growing up for me.''
