Report: Calvin Johnson told family, coach 2015 was his last season

Detroit Lions wide receiver Calvin Johnson told his family and head coach Jim Caldwell that 2015 was his last season, according to Adam Schefter of ESPN.

Johnson gave his head coach the message a day after the Lions' regular season ended with Caldwell reportedly telling Johnson to take his time with the decision, a source told ESPN.

The five-time Pro Bowler told only two teammates of his retirement plans during the season, asking quarterback Matthew Stafford and linebacker Stephen Tulloch to keep his decision private.

After another dismal 7-9 season, the seventh losing campaign of his nine-year career, Johnson relayed the information to the organization.

While no decision has been made official, Johnson's ailing physical health is thought to be a big factor in his consideration. General body soreness and persistent ankle and knee injuries have dogged Johnson over the past few seasons.

The Lions will carry a $12.9-million cap hit if Johnson proceeds with his retirement decision. The team released a statement on Sunday reiterating its respect for Johnson's eventual decision:

"Regarding today's ESPN report, we stand by our statement issued on Jan. 6 regarding Calvin."

On Jan. 6 the team stated, "We obviously have profound respect for Calvin and certainly understand and appreciate his decision to give proper thought and consideration to his football future."
