Manziel, who is on injured reserve with a hamstring injury suffered in Week 16, reportedly missed a team walkthrough and was late for treatment on Saturday after "throwing a big party Friday night attended by many members of the club," according to Jason La Canfora of CBS Sports.
Cornerback Justin Gilbert, who, like Manziel, was a first-round draft pick earlier this year, was also deactivated for Sunday's game after reportedly missing a team meeting on Saturday night. Gilbert has been criticized for his work ethic this season, including by Browns safety Donte Whitney, who said last week that Gilbert needs to "stop being a kid."
Left tackle Joe Thomas, who has been with the Browns for eight seasons, also echoed Haslam's criticism
The Browns lost to the Ravens 20-10, ending the season at 7-9. Cleveland at one time had legitimate playoff hopes, going 6-3 over its first nine games before losing six of the team's last seven games.
