Colin Kaepernick Not Investing In Ice Cube's BIG3 League ... Despite Report

Colin Kaepernick is NOT buying into the BIG3 -- despite a report the star quarterback was teaming up with Ice Cube to invest in the hoops league -- with a rep for Kap telling TMZ Sports the story is bogus.

On Wednesday night, Shams Charania reported 34-year-old Kap was stepping in as an investor to help Cube's hoops league, which the NBA insider said was "on the verge of potentially shutting down."

But, a rep for Kaepernick tells us the story just isn't true ... Colin is not working with BIG3.

Ice Cube -- alongside several business partners -- launched the league in 2017. The games feature mostly former NBA players -- many stars -- who play 3-on-3 games.

Cube: "The NBA hasn't been the nicest to the BIG3. Of course, publicly, they say all the right words. But we know privately, there's things done behind the scenes [with] sponsors, broadcasters, blah blah blah... It did tarnish my fandom a bit."

As for the league's reported struggles ... in an interview last month, the rap legend said the Association hasn't exactly been a supporter of the young league, saying the NBA "hasn't been the nicest to the Big3."

Cube continued ... "Of course, publicly, they say all the right words, Cube said, "but we know privately, there are things done behind the scenes [with] sponsors, broadcasters, blah blah blah. It soured me a little bit ... It did tarnish my fandom a bit."

Meanwhile, Kaepernick -- who hasn't played in the NFL since 2016 -- is still very interested in returning to the league where he once led the 49ers to the Super Bowl.

The Raiders held a tryout for the 34-year-old in May, and although they've yet to offer the QB a deal (or talk about the workout), Kap maintains he's ready if the Raiders, or any other NFL team calls him!
