BEREA, Ohio - The Browns are trying to trade former first-round offensive lineman Cameron Erving, a league source told cleveland.com.



Erving, the No. 19 overall pick in 2015 out of Florida State, was competing for the right tackle job before he suffered a calf injury last week that has him week-to-week.



Now, it's second-year lineman Shon Coleman's job.



Erving started 13 games last season, including 12 at center, where he struggled with the demands of the position. This preseason, he said he felt much more comfortable at right tackle, where he didn't have to be responsible for sliding the protections and all the other responsibilities of center.



Erving is under contract for two more years, with a club option for a fifth year. He's set to make almost $1.3 million this year, and $1.72 million next year.



Erving is one of a number of players being shopped by the Browns, including Pro Bowl cornerback Joe Haden.

Erving was one of two first-round picks in 2015 made by former Browns general manager Ray Farmer. The other was No. 12 overall pick Danny Shelton, who's starting at defensive tackle but is currently week-to-week with a knee injury.

If Erving is dealt, he'll join a long list of recent first-round picks since 2011 who are no longer with the team. It includes Phil Taylor, Trent Richardson, Brandon Weeden, Barkevious Mingo, Justin Gilbert and Johnny Manziel.
