Nike isn't backing down from its Colin Kaepernick ad campaign -- they just released a brand new 2-minute commercial featuring the QB -- and it's slated to air during the NFL season opener.
The spot features Colin narrating inspiring messages about overcoming the odds while real video of real inspirational athletes plays on the screen.
Colin references Serena Williams and praises her as "the greatest athlete ever" -- while throwing similar compliments at stars like Odell Beckham, Shaquem Griffin and the U.S. Womens National Soccer Team.
It's the second phase of Nike's "Just Do It" ad campaign featuring Kaep -- a deal that we're told was put together in the last several weeks.
