Johnny Manziel spent part of his downtime vacationing in Cape Cod.

The Cleveland Browns quarterback spent part of this past week working with former Tampa Bay Bucs and Oakland Raiders coach Jon Gruden in Tampa, concentrating on film work and mechanics.

The story was first reported by Charlie Campbell of WalterFootball.com and confirmed by a source with knowledge of the situation.

Gruden is an analyst for ESPN’s Monday Night Football, and part of his pre-draft work includes working with quarterbacks on the show Gruden's QB Camp.

Manziel's decision to work with Gruden is another step toward putting a disastrous rookie season behind him. He was ineffective in two starts and a distraction off the field. Shortly after the season, Manziel spent 10 weeks at a treatment facility. He has moved his residence and been much less of a public presence on social media.

Manziel admitted his public persona overtook him last season. He even said he'd eliminate his signature money sign that helped make him "Johnny Football" in college.

Browns quarterbacks are to report to camp on Monday, with the first full-team practice open to the media and public set for Thursday.

Josh McCown opens camp as the firm starter. Manziel figures to be the backup, competing with Thad Lewis and Connor Shaw.

What does Gruden think of Manziel?

"I want Manziel,” Gruden said in a conference call prior to the draft last season.
