It was a huge blow to Reebok when Nike took over, in 2012, as the official apparel sponsor of the NFL. But Reebok still had a big NFL contract in its back pocket: Peyton Manning.

Suddenly, though, it looks like Manning will no longer be throwing touchdown passes in Reebok cleats. According to Darren Heitner, a contributor to Forbes, Manning has left Reebok.

Heitner went one-step further and posted a picture of Manning in a pair of Under Armour sneakers.

Is Reebok done in the NFL?
