Kneeling during the National Anthem is back in the spotlight on the sidelines of the NFL.   But will the pitiful protest show up at the big fight?

Pop singer Demi Lovato will sing the national anthem before the multi-million dollar main event featuring boxing champ Floyd Mayweather and mixed martial artist Conor McGregor .

Lovato says she has never performed the National Anthem at a boxing match.  But then this is no ordinary "boxing match".   It will be interesting to see how much respect is shown the flag and anthem in an environment of total disrespect by the participants!

The showdown gets down on Showtime pay-per-view on Saturday night.
