After an incredible start for USA Boxing, things have slowed down for the American team. Day 10 at the Rio Olympics saw two more fighters fall.

Both Mikaela Mayer and Antonio Vargas lost on Day 10, with Mayer losing in the quarterfinal and Vargas in the round of 16.

Vargas gave all credit to his opponent Shakhobidin Zoirov.

“(Zoirov is) a good boxer,” Vargas told NBC Sports’ Chris Mannix. “He's a real awkward southpaw. It was a close fight but I wasn't mad that they gave (the decision) to him.” 

Mayer came up short to her Russian opponent Anastasiia Beliakova.

In a surprising outcome, Irish medal favorite Katie Taylor fell in her quarterfinal matchup against Finland’s Mira Potkonen. The 2012 Olympic champion in the lightweight division lost a 2-1 split decision.

“That's life,” Taylor told Mannix. “I've had a great run and have been so consistent through the years. It's hard to keep that consistency going. I prepared as best as I could. I gave everything in there. That's all I can do.”

Another gold medal was crowned in the final fight of the evening session as Russian Evgeny Tishchenko defeated Kazakstan’s Vassiliy Levit via unanimous decision.
