DAVIE, Fla. (AP) Miami Dolphins tight end Jordan Cameron will be placed on injured reserve Saturday and miss the rest of the season because of a concussion that threatens his career.

Cameron has been sidelined since his injury in Week 3 and has been seeing a concussion specialist in Pittsburgh. He said this week he was improving, and he hoped to return this season, but the Dolphins decided to replace him on the roster.

The concussion was at least the fourth for the 28-year-old Cameron since he joined the NFL in 2011.

Cameron made the Pro Bowl with Cleveland in 2013, but has totaled only 43 catches and four touchdowns in two years with Miami.
