The UFC president said Friday on FOX Sports Live that he wants Hendricks, the former welterweight champion, to move up after a weight-cutting mishap this week forced him out of his fight with Tyron Woodley at UFC 192 on Saturday.
"He blows up," White said. "He blows up when he's not competing. As you continue to get older, it gets harder to make the weight. He has to figure out a diet. He just lost a huge opportunity here tonight. He needs to figure this thing out. I consider him a (1)85-pounder right now. I do not want to see him at 170 again.
Hendricks pulled out of the fight Friday after being rushed to the hospital Thursday. Hendricks' manager Ted Ehrhardt told MMA Fighting's Ariel Helwani that Hendricks suffered a blockage of his intestine and a kidney stone.
"They called me last night and said he was in a lot of pain," White said. "He laid down and he was better when he laid down and he felt less pain. I said take him to the hospital. They didn't want to take him to the hospital because he was dehydrated and they would give him an IV. It's not worth it. It's not worth a dangerous weight cut to come in and fight no matter how big the fight was. This was a big one."
Hendricks told Helwani that his weight cut was going well this time until Thursday. This is not the first time "Bigg Rigg" has had these problems. He missed weight on his first attempt at UFC 171 in March 2014 before a fight for the vacant title with Robbie Lawler. Hendricks did eventually make it to 170 on the second attempt.
"The weight was coming off fine and then yesterday my body just started to shut down," Hendricks said. "When it hit that point, I tried to push through it, and well, it didn't go well because then I had to go to the ER."
Hendricks, 32, told media this week that he was a little north of 185 pounds and en route to making weight. White told a different story.
"Tuesday he came in he was 26 pounds overweight," White said. "That's a huge weight cut. We try to discourage those type of weight cuts but these guys run their own camps.
"He's got a lot of lifestyle changes to make, and he's got to get serious. He's not 20 anymore."
White told Kevin Iole of Yahoo! Sports earlier Friday that Woodley would be getting the next title shot after Lawler defends his belt against Carlos Condit at UFC 195 on Jan. 2. The boss was non-committal on FOX Sports 1, though.
"He's next in line, but there a lot of different variables involved," White said. "Robbie and Condit are fighting already on Jan. 2 in Las Vegas. What if one of them gets hurt after the fight? There's a lot of different timing variables. [Woodley] hasn't fought in a long time. He's got to fight, he's got to make money. He's next in line, but there's a lot of variables to get into that title."
White was also not sure about giving Woodley his show or win money, saying they would work something out. Woodley weighed in at 170 pounds Friday as scheduled, though his fight was canceled.
