An NFL owner testified under oath during a collusion grievance deposition that he changed his mind on signing Colin Kaepernick following remarks made by Donald Trump about firing players who protest during the national anthem.

Kaepernick filed a grievance last October against NFL owners for collusion.

Attorney Mark Geragos told the “Straight Aim” podcast Tuesday that the unidentified owner's testimony proves collusion.

"In this civil case, there’s no doubt that the existing coaches — and I’m talking about Super Bowl-winning coaches — have testified under oath that he’s a starting quarterback in this league, and so that’s mind boggling,” Geragos said. “When you ask them … specifically why he isn’t he being hired … they say because of the national anthem policy.

"The only reason — and the owners will admit that — they haven’t signed him is they’re afraid of Trump, and they’ve colluded because of Trump,” Geragos said.
