There’s at least one reason Calvin Johnson wasn’t happy with how the Detroit Lions handled his retirement last year.

Johnson paid the Lions back at least $1 million from his signing bonus when he retired from the NFL in March 2016 – much more than the team was entitled to – according to a source of Carlos Monarrez of the Detroit Free Press.

NFLPA records had shown Johnson paid the Lions just $320,000 – approximately the amount they were entitled to upon his retirement under the collective bargaining agreement.

Back in May, Johnson said he rarely speaks to the Lions organization based on the way their relationship ended:

“I just didn’t feel like I was treated the way I should have been treated on the way out. That’s all. I mean, it’s all good. I’m not tripping. I don’t feel any kind of way, just ‘Hey, that’s what they did. Hey, it is what is,'” Johnson said.

Johnson holds numerous Lions and NFL records, including the most receiving yards in a single season when he racked up 1,964 yards in 2012. The 31-year-old was named to six Pro Bowls over the course of his career.
