Cleveland Browns quarterback Johnny Manziel is expected to be a full participant in training camp this summer.

The Browns star spent 10 weeks in rehabilitation after a turbulent rookie year, but offensive coordinator John DeFilippo has been impressed with him.

"He's spent every hour that he's been allowed to spend in this building," DeFilippo told reporters.

"I can't predict the future, but all I can do is tell you right now Johnny Manziel is putting himself in a position to be a quarterback in the NFL."

Manziel completed 18 of 35 passes for 175 yards and two interceptions in seven quarters of play in his first year in the league.
