Knee replacement surgery last week will leave Bob Arum to watch the Terrence Crawford-Yuriorkis Gamboa fight from a comfortable chair Saturday night, far away from Omaha, Neb.

“The thing I like about this fight is this is not just a title defense or an appearance fight,” Arum said. “This is the best two lightweights in the world. I think it’s a tremendous fight. I like Crawford’s chances. A lot of people like Gamboa’s chances. It’s a real, real fight.”

Arum’s Top Rank Inc. promotes Crawford, who is on the cusp of breaking through as a legitimate gate attraction in Omaha, his hometown.

“I was very impressed with Crawford against Ricky Burns,” Arum said of Crawford’s title-winning performance, a unanimous-decision defeat of Scotland’s Burns (36-4-1, 11 KOs) on March 1 in Glasgow. “And I was impressed with him when we had that fallout on the card last year and we needed to find a guy to go on HBO against [Breidis] Prescott. I pushed for this guy because I realized he has a lot of talent. So far he has come through tremendously. He is really a talented, talented young man. From all I can see about him, he has great, great Midwestern sensibilities and habits.”

Crawford (23-0, 16 KOs) is a slight favorite, presumably because he is bigger and has a perceived hometown advantage over Gamboa (23-0, 16 KOs), a Cuban-born Miami resident promoted by rapper/actor 50 Cent.

Russia’s Matt Korobov (23-0, 14 KOs) and Venezuela’s Jose Uzcategui (22-0, 18 KOs) will square off in the opener of HBO’s “Boxing After Dark” doubleheader Saturday night (10 p.m. ET/7 p.m. PT).
