Calvin Johnson says his health was the main reason why he opted to retire with several productive years still likely ahead of him.
"I know everybody wants to know why I retired, but it's more so I put a lot into the game and it's taken a lot out of me and that's where I'm at right now," Johnson said. "I'm not getting into the specifics of the things that it has taken away, but it definitely feels good, I guess I could say for myself, to spend more time around my family, my son, just got married.
"Things are going good right now."
Johnson caught 731 passes for 11,619 yards and 83 touchdowns in his career.
"I'm not coming back," Johnson said. "You ain't gotta worry about that."
