Anderson, who is competing with Brady Quinn for Cleveland's starting quarterback job, missed the final two days of mandatory minicamp in June after injuring his right calf.

Anderson finished minicamp with a limp and a heavy wrap on his leg, and neither Anderson nor Browns coach Eric Mangini would discuss the severity of the ailment.
But a source told ESPN.com on Friday that, after a month of rest and rehab, Anderson's health is no longer an issue.
Cleveland's full team will practice for the first time in training camp Aug. 1.
Anderson made the Pro Bowl in 2007 after throwing for 3,787 yards, 29 touchdowns and leading the Browns to a 10-6 mark. But he couldn't duplicate those efforts last season, which opened the door for Quinn, a former first-round pick from Notre Dame.
Both quarterbacks have a clean slate this summer under a new regime. The Browns gave Quinn the slight edge when the pair began practices this offseason, but the team likely will not make a firm decision until late in the preseason.
