The discussion comes on the heels of Dantas’ first-round knockout loss on Aug. 25 to Tyson Nam at Shooto Brazil 33 in Rio de Janeiro.
Bellator will begin airing its fights on Spike TV in January. Rebney did not specify the exact date of the promotion’s network debut.
“We might end up bumping that fight back a little bit and doing it on Spike TV when we premiere in January,” Rebney said. “The alternative is to keep it where it is right now, which would literally be in 2½ months.
“But there’s probably an eye toward delaying it. I’m not officially saying it’s switching but we will have to look at the circumstances and give some very serious consideration to delaying it.”
Dantas (14-3) was knocked out by a counter right hook from Nam. It was his first loss since July 19, 2009, when Masakatsu Ueda beat him by unanimous decision in a Shooto bout.
“Whenever a knockout like that occurs, most fighters -- they’re athletes, they’re champions -- want to get right back in the cage as quickly as possible,” Rebney said.
“As you’ve seen with the steps we’ve taken with Joe Warren and others, when you get a serious knockout you need to take some time to reflect to take the proper precautions in terms of timing. So [Dantas] isn’t doing any sparring anytime soon. He’s going to take a breather.”
Dantas lifted the 135-pound belt from Zach Makovsky with a second-round submission on April 13.
Galvao (13-5) earned the title shot on Aug. 24 when he knocked out Luis Alberto Nogueira in the second round to win the Bellator Season 6 Bantamweight Tournament.
