Part of Calvin Johnson's retirement tour? Meeting Michelle Obama

Calvin Johnson has been pretty quiet in the almost three months since he announced his retirement through a press release in March.

Sure, his teammates recognize the void without him and are still being asked questions about him, but the former Detroit Lions star receiver and the NFL's single-season record holder for receiving yards (1,964 in 2012) has been mostly silent.

There have been a few Instagram pictures of trips to San Diego and Tampa, Florida, and a couple of well-placed photos of Pizza Hut and Boxed Water. And on Wednesday, he posted a picture of himself with a very familiar face -- first lady Michelle Obama -- along with his fiancée, Brittney McNorton, and Todd Krim, whose website notes that he connects celebrities with charities.

The photo was taken at an event Johnson attended with the first lady in April in New York City for national signing day for high school seniors. Johnson is wearing a Georgia Tech T-shirt in the photo, and Obama is wearing a Princeton T-shirt. It's the second time since his retirement he has referenced the first lady on Instagram -- the first coming soon after the actual event, where he described what the scene was like.

So while Johnson has been quiet about his post-football plans, this all could offer a glimpse into what his future might hold. His foundation, the Calvin Johnson Jr. Foundation, has been heavily involved with educational programs in Atlanta and Detroit, and it is something Johnson has always been passionate about. Johnson also talked openly before retiring about obtaining his degree from Georgia Tech.

Or it could just be a great picture of him with the first lady of the United States.

Either way, it's the start of a big month for Johnson, who is expected to marry his McNorton later this month.
