Charles Woodson, the Michigan football icon and 1997 Heisman Trophy winner, announced on Instagram on Thursday his tenure as a talking head on ESPN has come to a close.

In Woodson's video, he thanked his on-air colleagues — Sam Ponder, Randy Moss, Matt Hasselbeck and Rex Ryan — with whom he shared the "Sunday NFL Countdown" set the last three years.

Woodson went straight from the playing field, retiring from the NFL after the 2015 season, to the studios in Bristol, Conn.

During the last three years, Woodson has been selected to the 2018 class of the College Football Hall of Fame, was put in Michigan's Hall of Honor in 2017 and was the guest speaker at U-M's spring graduation last year.

In that speech at Michigan Stadium, Woodson famously guaranteed U-M would beat Ohio State in 2018. Six months later, the Wolverines lost in Columbus, 62-39.

As for what's next for Woodson, 42, the former All-Pro defensive back said: "I’ll see you next season somewhere. Stay tuned."
