NBC Sports announcer Chris Marlowe has apologized after calling Brazillian beach volleyball player Larissa Franca’s same-sex spouse her “husband” on air during the network’s Rio Olympics coverage on Tuesday.

After Franca and her volleyball partner Talita Antunes defeated U.S. volleyball players Lauren Fendrik and Brooke Sweat in a match, Franca went to hug her wife Liliane Maestrini.

Marlowe described the scene to viewers by saying “She gives a hug to Lili. That is her husband. She married Lili in 2013.”

Social media was outraged by the flub, including former NBA player Jason Collins. Collins came out in 2013, becoming the first openly gay U.S. professional athlete to come out during his career.

I saw this live and was confused when the commentator said “husband”. C’mon @nbc @NBCOlympics @NBCSports #DoBetter ? https://t.co/UYJC0qfiOf

Marlowe took to the same platform to apologize for his mistake.

“I’m sorry for the mistake today. Clearly, Liliane is Larissa’s wife,” Marlowe tweeted.
