Jordan Cameron is calling at a career.

The veteran tight end, who signed a two-year, $15-million contract to join the Miami Dolphins in 2015, was limited to just three games this past season after suffering a fourth concussion.

Concerns over the head injuries led him to opt for retirement after just six seasons in the NFL.

“I started thinking about concussions too much,” Cameron told ESPN’s Pat McManamon on Friday. “You can’t play football like that.”

Cameron, a fourth-round pick in the 2011 draft, played the first four years of his career with the Cleveland Browns. His ability was never in doubt, and it likely still isn’t.

But the 28-year-old says continuing to play and exposing himself to the possibility of further injury isn’t worth the risk.

“If I didn’t get concussions I’d probably keep playing,” Cameron said. “It’s one of those things. I can’t risk my mental health in the future. I don’t have any symptoms now. I’m perfectly fine. But they can’t tell me with 100 percent certainty that if I keep playing and I get more concussions that I’m going to be OK. I’m not risking that at all. There’s nothing more important than your health. It’s just not worth it to me.”

Cameron’s career comes to an end having played in 66 games, tallying 173 receptions for 2,046 yards and 14 touchdowns.
