Terence Crawford will have to wait a little bit longer to make his welterweight debut.

THE RING’s junior welterweight champion suffered a right hand injury in training and will be sidelined for two weeks, Top Rank CEO Bob Arum told THE RING on Wednesday. Crawford was set to challenge Jeff Horn for his 147-pound title on April 17 in Las Vegas, but that bout will now be rescheduled.

“There’s no ligament tear, nothing, he took the MRI and so forth,” Arum said. “He has to rest it for a couple of weeks. So we’ll probably do it sometime in May or maybe the first weekend in June.”

Arum said the fight will move to a date in May or June 2. With Canelo-GGG 2 on May 5 and Jorge Linares-Vasyl Lomachenko the following weekend, that leaves May 19 and May 26 (Memorial Day) as other possibilities.

The junior featherweight title bout between Jessie Magdaleno and Isaac Dogboe was set to appear on the Horn-Crawford undercard, but that fight will now move to April 28 in Philadelphia and serve as the ESPN main event, according to Arum.

The other bout ticketed for the show, an all-Filipino junior bantamweight title bout between Jerwin Ancajas and Jonas Sultan, will likely still be paired with Horn-Crawford, Arum said.

Crawford (32-0, 23 knockouts) became undisputed champion at 140 pounds with a third-round knockout of Julius Indongo in August, but now the 30-year-old wants to chase supremacy in a far deeper weight class.

In Horn, Crawford will face a tough, rugged Australian who defeated Manny Pacquiao last summer, albeit via controversial decision. Horn (18-0-1, 12 KOs) isn’t nearly as skilled as Crawford, but he’s a large welterweight, and he figures to weight much more than “Bud” on fight night.
