The relationship between UFC fighters Ronda Rousey and Travis Browne seems to be going great. It’s their results in the octagon that are a disaster.

At UFC 213 on Saturday night, Browne was submitted in the second round by Russian fighter Oleksiy Oliynk. The loss extended Browne’s losing streak to four, and now he’s being asked to retire by UFC president Dana White.

The happy couple, who got engaged this spring, went public with their relationship in October 2015. Browne won his next fight, in January 2016, then came a precipitous fall from the top of the UFC heavyweight rankings.

Rousey also has experienced an in-ring downward spiral since pairing up with Browne. In late 2015, Rousey was the UFC’s bantamweight champion and the undefeated megastar of the sport. She hasn’t won since, suffering the infamous head-kick knockout loss to Holly Holm in November 2015 and most recently, a 48-second defeat by Amanda Nunes last December.

“This is one of those sports, you never know. One minute you’re absolutely unbeatable and unstoppable, then the next minute you can’t win a fight,” White said after Browne’s loss at UFC 213.

“I think that Travis should retire.”

Browne has yet to respond to White’s comments. White previously said he does not expect Rousey to fight again — she has spent much of the past year on pursuits in the entertainment world — though she has not officially retired.

“She hasn’t told me she’s retiring,” White said in April, “but I don’t think she’s [coming back].”
