Terence Crawford knocked down Errol Spence Jr. three times Saturday night before finally ending the fight at 2:32 of the ninth round on a technical knockout to cement himself as one of the greatest welterweights in history.

A mythical sparring session with Michigan boxing legend Floyd “Money” Mayweather Jr. has set the stage for the Errol “Big Fish” Spence Jr., Terence “Bud” Crawford legacy fight in Las Vegas.

Errol Spence Jr. and Terence Crawford meet Saturday night in Las Vegas.

Terence Crawford has been asked for years when he would fight Errol Spence Jr. A match between the undefeated fighters would make the winner the undisputed welterweight champion and give him a claim as the best in the sport, so it was one of the biggest bouts that could be made.

Unbeaten world champion Terence Crawford knocked out David Avanesyan in the sixth round to retain his WBO welterweight belt.

Canelo Álvarez’s trilogy-ending victory over Gennady Golovkin was not an unforgettable classic in the ring.

Errol Spence Jr. became a three-belt welterweight champion by defending his WBC and IBF titles in a unification bout in front of a home crowd when his bout against Yordenis Ugás was stopped in the 10th round because of the WBA champ’s right eye that was almost completely swollen shut.

Yordenis Ugás beat Manny Pacquiao by unanimous decision.

Almost nobody in the history of boxing could even conceive of doing what Manny Pacquiao intends to accomplish over the next year.

Yordenis Ugás is finally living the life he imagined when he decided to leave Cuba.

Manny Pacquiao could have postponed or canceled his boxing comeback when opponent Errol Spence Jr. dropped out less than two weeks before their Aug. 21 showdown.

Errol Spence Jr. has dropped out of his pay-per-view fight with Manny Pacquiao on Aug. 21 because of a retinal tear in his left eye.

The rebranding of Floyd Mayweather Jr. is taking another unconventional turn.

Canelo Alvarez added another title belt in the super middleweight division, handing Billy Joe Saunders his first loss when the English boxer didn’t come out for the ninth round.

(AP Photo/Brandon Wade)ARLINGTON, Texas – Errol Spence Jr. skipped a tune-up in his first fight since a car crash that almost derailed his promising career. Garcia tried to surge late, landing a right near the end of the 11th round that sent Spence looking for his corner just as the bell sounded with Garcia closing in for more. Spence pinned Garcia on the ropes with a series of blows before Garcia escaped and steadied himself before the end of the round. Spence landed 187 punches, or 26%, to 117 and 17% for Garcia, and had a huge edge on jabs.

What Crawford is still waiting on is the one signature fight that will put an end to all those arguments. Crawford won’t get that Saturday night when he defends his piece of the welterweight title against England’s Kell Brook. “I’m optimistic that if Terence wins, we can put the fight on and if Terrence doesn’t win and Kell Brook wins, maybe I’ll make Kell Brook with Manny,’’ Arum said. Crawford is a huge favorite in Las Vegas sports books to beat Brook, who is coming down from his recent weight of 154 pounds to challenge Crawford. ``I think Terence knows I’m not an easy fight,’’ Brook said.
