Can anyone be really nervous enough to pee on their pants? Recently, American boxer Brandon Rios has revealed that he almost suffered a fear-induced urination before his fight with eight-division Filipino boxing champion Manny Pacquiao.

That need to urinate is one of the weirdest symptoms of nervousness. In an interview with Fight Hype, Rios shared a humorous story about how he still gets butterflies in his stomach every time he steps in the ring and how he almost peed himself walking into the ring with Pacquiao.

"I almost peed myself walking in the ring with Pacquiao," Rios said when asked if he still gets a little anxious before a fight. "I'm serious."

According to Rios, he usually feels good ahead of a fight. However, he feels a little tense and edgy the moment that he steps into the ring, especially when he is set to fight one of the biggest names in boxing like Pacquiao, for instance.

Rios fought Pacquiao in November 2013 for the vacant World Boxing Organization or WBO, International Welterweight title at The Venetian Macao resort and casino in Macau, China. He was guaranteed a purse of $3 million for the fight. It was reportedly the highest prize money that Rios has ever received in his boxing career.

Rios is set to face his rival Mike Alvarado for the third time on Jan. 24 in an HBO televised main event at the 1stBank Center in Broomfield, Colorado. Currently, Rios and Alvarado are tied at 1-1 and Rios is determined to settle trilogy with a convincing victory.

In October 2012, Rios (32-2-1, 23 KOs) defeated Alvarado (34-3, 23 KOs) with a seventh-round knockout. Alvarado, on the other hand, has inflicted vengeance by scoring a victory via unanimous decision in their second meeting to win the vacant junior welterweight title.

Rios is currently in the last piece of his training for the Alvarado fight and he said that he is more than prepared and read for the third clash. Rios said everything in his training is going great and he feels good leading up to the Jan. 24 fight.
