CLEVELAND (92.3 The Fan) – The Johnny Manziel situation with the Cleveland Browns is spiraling out of control.

Browns owner Jimmy Haslam confirmed Sunday night that that Manziel missed a 9 a.m. scheduled appointment at the team’s headquarters for treatment Sunday morning. Manziel was entered into the NFL’s concussion protocol last Wednesday and ruled out Thursday for the season finale that saw the Browns lose 28-12.

According to ESPN Las Vegas, Manziel was spotted at a Vegas club on the strip wearing a blonde wig, fake mustache, glasses and hoodie as a disguise while he partied into the night.

The Browns are not commenting on this latest report and have avoided directly addressing the latest fiasco surrounding their 2014 first round pick.

According to the report, Manziel allegedly introduced himself as “Billy” but the jig was up when it came time to pay his bill, which he reportedly requested be comped to his room but instead had to use his credit card because he did not have enough cash.

Manziel tried to quiet buzz Saturday night that he was in Vegas by posting a picture of him laying on the floor with his dog nearby on his Instagram account with the location tag of “Avon, Ohio” which can manually be entered.

Former head coach Mike Pettine, fired Sunday night, denied that Manziel showed up to the facility last Wednesday inebriated during his final post game press conference when he was asked but the current rumors raise serious questions about the 2012 Heisman Trophy winner.

Several players said Monday as they cleaned out their lockers that those in the concussion protocol do not attend games because they are not permitted on the sideline per NFL policy and would have to watch the game from a suite, so many opt to just stay home.

While the Browns remain mum publicly, they may have reached a point where they simply ask Johnny to just stay home.
