While the entire boxing world is on hold because of the upcoming Floyd Mayweather vs. Manny Pacquiao fight, many other great Welterweight fighters are still scheduling their next bout.

Some of the most notable welterweight boxers who still don't have a scheduled fight include Keith Thurman, Juan Manuel Márquez and Timothy Bradley.

All three of these boxers rank in the top 10 in their weight class, and we may see them collide this year:

Keith Thurman

What a promising career start Thurman has shown.

In his last win, Thurman defeated Robert Guerrero to extend his career record to 25-0-1. He didn't knock out Guerrero, but it was an very impressive technical bout by "One-Time" to retain the Interim WBA Welterweight title.

Thurman is currently ranked No. 4 in the Welterweight division behind Mayweather, Pacquiao and Márquez. Thurman knows he has the strength and knockout power to compete against Mayweather and Pacquiao, but that's going to have to wait at least another year. An upcoming fight against Márquez or Bradley would be just another chance for Thurman to display his greatness in front of everyone.

Still just 26 years old, Thurman knows he's the future of Welterweight boxing considering the fact the Mayweather (38) and Pacquiao (36) are nearing retirement. Thurman has called out Bradley in the past saying, "Tim Bradley was lucky that he wasn’t fighting me that fight, that would have been one of the easiest nights to grab a belt. As soon as I get my hands on him, it’s over." That was in reference to Bradley's win over Ruslan Provodnikov.

Juan Manuel Márquez

It's been a great career for the 38-year-old out of Mexico City, Mexico. Juan Manuel Márquez is a tough fighter who likes to get in close and trade blows. He can dish it, and he can take. His most notable victory came against Pacquiao in 2012 when he knocked him out in the sixth round.

Márquez has options, and retirement is one of them. It's hard to blame Márquez for considering hanging up the gloves because he's accomplished so much. Márquez has 56 career wins and seven losses with 40 knockouts. He is presently the No. 3 ranked fighter in the Welterweight division thanks to his last win against Mike Alvarado in May of 2014.

If Márquez wants give it one more year, he could consider facing Bradley or Thurman. Pacquiao will definitely want a revenge match against Márquez, but there's no certainty in that. Márquez and Bradley faced each other in 2013 with Bradley winning by split decision. A rematch could be in the making.

Timothy Bradley

Ever since Bradley's win over Márquez in 2013, he's fallen off in the rankings. Since that fight, he lost to Pacquiao and drew a tie against Diego Gabriel Chaves. Bradley is now ranked No. 9 in the Welterweight division, but many boxing fans feel that "Desert Storm" is much better than that.

Although he was ruled the victor over Pacquiao in 2012, it was a very controversial decision.

Bradley is still 31 years old, and he is very quick. It's been more than a year since Bradley won a fight, and he knows it's time to redeem himself. A second bout against Márquez would be interesting, but a victory over Thurman would do wonders for his career. Rumors have circulated that Bradley could face Miguel Cotto in his next fight.

Kell Brook is the No 5 ranked boxer in the Welterweight division, but he is schedule to face Jo Jo Dan on March 28.
