Watch: Daniel Cormier sings the national anthem after losing a challenge to Laura Sanko at UFC 266 weigh-in show

Daniel Cormier sang the US national anthem after losing a challenge to fellow UFC analyst Laura Sanko during the UFC 266 weigh-in show.

Check out the video below:

DC, Sanko, Paul Felder, Din Thomas and others on the UFC 266 weigh-in show set hosted multiple fighters over about two-and-a-half hours. During a segment of the show that featured reigning UFC women's flyweight champion Valentina Shevchenko, the hosts tried the shuffle dance.

They appointed Shevchenko, who's a trained dancer, as the judge. Following this, Paul Felder, Laura Sanko, Daniel Cormier and Din Thomas put forth their best attempts at performing the shuffle dance. They then asked Shevchenko to rate their performances and reveal who she thought were the best and worst.

Shevchenko asserted that Sanko was the winner of the shuffle dance challenge. 'Bullet' praised everyone and refrained from saying whose performance was the worst. Regardless, Laura Sanko and others jestingly noted that Daniel Cormier's performance was the worst.

Cormier was punished and made to spin 'The Wheel of Misfortune,' which is a part of a lighthearted game segment on the show. Shevchenko spun the wheel for Cormier, and once it came to a stop, it was revealed that DC would have to sing.

Laura Sanko asked Daniel Cormier to sing 'The Star-Spangled Banner,' the US national anthem. Cormier obliged and the others joined in. DC was even handed a mobile phone, presumably to view the anthem's lyrics.

While Cormier initially joked around and insinuated he'd need others to help him sing, the MMA legend went on to complete the song in impressive fashion.
