Cleveland — Johnny Manziel is back at work after a holiday weekend in Las Vegas.

And when you’re Johnny Football, what happens in Vegas doesn’t necessarily stay in Vegas.

The celebrated Browns rookie quarterback reported for organized team activities Tuesday following a few days in Vegas, where he kicked off his summer by hanging poolside with Patriots tight end Rob Gronkowski, attended a UFC fight and was captured on video spraying champagne on patrons in a nightclub.

And, according to Manziel, he found time to study his playbook.

Following his first practices with Cleveland’s veterans last week, Manziel took advantage of a break in the workouts to head to Las Vegas. On Saturday, a photo of him and Gronkowski, surrounded by other partiers, appeared on several social media sites.

Later, Manziel posted a photo on his Twitter account of him standing with UFC president Dana White and a thank you note.

Although this was all done on his time, and Manziel didn’t commit a crime or have any known issues, his actions raised eyebrows in some circles about his commitment to playing in the NFL.

He seemed to fire back at any criticism by posting a photo on his Instagram account of his Browns playbook and iPad with the caption: “Guess it’s impossible to enjoy the weekend and study?”

Manziel, selected 22nd overall by the Browns after sliding in the first round, is expected to challenge Brian Hoyer (Michigan State) for the starting job.
