The Cleveland Browns have released Brian Hartline.

Hartline struggled to gain separation and was a below replacement level wide receiver.

First-round pick Corey Coleman is in line to be the team's leading receiver, with Andrew Hawkins the remaining veteran.

The San Diego Chargers have claimed Zach Mettenberger off waivers.

Mettenberger was waived this week by the Tennessee Titans.

The Chargers held the No. 2 waiver wire priority behind the Cleveland Browns and reunite Mettenberger with Ken Whisenhunt.

Mettenberger offers prototypical pocket quarterback size, a big arm and a willingness to squeeze the ball into tight spaces. Mettenberger has a QBR of just 16.5 over the past two seasons.

The Carolina Panthers have released Brandon Boykin.

Boykin signed a one-year, $840,000 deal in March with the Panthers.

Boykin started just one game in Pittsburgh last season after several solid seasons as a slot corner in Philadelphia.

Zach Mettenberger has been waived by the Tennessee Titans.

Mettenberger started 10 games over two seasons. The Titans didn't win any of those games.

Mettenberger, who has a big arm but limited mobility, completed 60.3 percent of his passes with 12 touchdowns, 14 interceptions and a 75.4 passer rating for the Titans.

Marcus Mariota will be the starter again this season while the Titans signed Matt Cassel as his backup when free agency opened.

The Tampa Bay Buccaneers have cut Connor Barth after selecting another kicker in the second round of the draft.

Roberto Aguayo became just the fourth kicker in the past 25 years to be selected in the second round or higher.

Barth made 23-of-28 FG attempts after replacing the ineffective Kyle Brindza.
