Cleveland Browns quarterback Johnny Manziel reportedly is struggling in training camp.  Manziel, who made headlines throughout the summer for his partying, supposedly has the Browns concerned about his regression in practices.

Manziel appears destined to start the season on the bench.

Per ESPN:

"The numbers tabulated each day by ESPNCleveland's Jason Gibbs have not been pretty.  Gibbs has charted all plays in 7 on 7 and team drills.  Unofficially, Manziel has completed 42 of 85 passes (49.4 percent).  He has been 'sacked' two times officially.  Two other obvious sacks were waved off and resulted in Manziel interceptions.

"There has been one other interception, four keeper runs by Manziel and three plays aborted by general confusion.  Manziel's only touchdown pass came on a little flip to fullback Ray Agnew off a bootleg.  It's too early to draw conclusions.  But it's nearly impossible to make the case that Manziel has earned first-team reps."

Granted he's a rookie and it's his first training camp, his lack of production during practices obiously hurts his chances of supplanting incumbent starting quarterback Brian Hoyer.  Even more alarming, Manziel reportedly is regressing on the field and has the Browns coaches growing concerned about his off-the-field activities.

"The Browns have been 'alarmed' by some of Johnny Manziel's antics since the draft -- especially a photo of him rolling up a $20 bill in the bathroom of a bar -- and some in the organization feel he's lost ground in the quarterback competition heading into camp, sources have told the Northeast Ohio Media Group," Mary Kay Cabot of Cleveland.com wrote Friday.  "... Manziel regressed in practice after the first week of organized team activities, and some in the organization attributed it to too much jet-setting and not enough dedication to the playbook."

Manziel does have the opportunity to wow his coaches on Saturday, when he will play in the team scrimmage at the University of Akron.
