The Detroit Lions all-time leading receiver is calling it a career. Calvin Johnson retired on Tuesday after a 9-year career in which he achieved 15 NFL records

"After much prayer, thought and discussion with loved ones, I have made the difficult decision to retire from the Lions and pro football. I have played my last game of football.

Johnson racked up 731 receptions for 11,619 yards and 83 touchdowns during his illustrious career. Johnson also holds the NFL record for most receiving yards in a season with 1,964 yards.

"Let me assure you that this was not an easy or hasty decision. As I stated, I, along with those closest to me, have put a lot of time, deliberation and prayer into this decision and I truly am at peace with it.

Johnson was the No. 2 overall pick of the Lions in the 2007 NFL draft, selected just after the Oakland Raiders took JaMarcus Russell. How laughable is that Raider blunder?

The Lions will save at least $11.1 million in cap space with Johnson's retirement. Although he may not be a first ballot Hall of Famer, he will be wearing a gold jacket some day.

"I also want you to know that I have the utmost respect and admiration for the game of football. It has provided so much for me and my family and I will be forever grateful to the game."
