Betting controversy arises during Super Bowl national anthem

The first controversy of Super Bowl LIII has surfaced, but it's not tied to the game itself.

Gladys Knight's rendition of the national anthem clocked in unofficially at 2:01. Most betting sites have the over/under at 1:50, meaning the anthem hit the over.

However, Knight might have said the word "brave" twice. One sportsbook awarded the over as a win, but later took it back due to the repeat word, according to Action Network's Darren Rovell.

If only one "brave" was sung at the end, the under would have hit. Some books are awarding the anthem as an under, ruling that the song ended before Knight said "brave" for a second time, according to OddsShark.
