Cameron (concussion) announced his retirement Friday, NFL.com reports.

EDGE Analysis

A fourth-round pick in the 2011 draft, Cameron emerged in a big way during the 2013 season, catching 80 passes for 917 yards and seven touchdowns for an otherwise unremarkable Cleveland team. He's subsequently been hampered by a series of concussions, which arguably impacted his play even when he was healthy. Cameron acknowledged as much in his retirement statement, saying he had started thinking about the concussions while on the field. He'll wisely put his long-term health above the possibility of squeezing out a few more seasons, hanging up his cleats at the age of 28. The Dolphins have already moved on, acquiring pass-catching tight end Julius Thomas in a February trade with the Jaguars.
