Dave Chappelle says his Sundays are definitely NOT filled with football -- telling TMZ Sports he's off the NFL and it seems it all has to do with Colin Kaepernick.
We shot the comedian out on Sunday and asked if he'd be checking out the games later on -- but he told us the NFL ain't on his schedule ... and then took a knee, just like Colin.
Chappelle has publicly show support for the QB -- he even wore a Kaepernick shirt to his big stand up show at Radio City Music Hall in 2017.
