Heartbreaking news surfaced early Tuesday morning that former UFC title challenger Chael Sonnen‘s daughter was born 10 weeks premature and is currently fighting for her life.

Sonnen, who recently celebrated the end of his 2-year suspension, had been MIA on social media for several days before news broke of his daughter’s premature birth.

While details are scarce at the moment, stay tuned for updates on the situation.

Please send thoughts & prayers to @ChaelSonnen & @BrittanySonnen for their baby girl born 10 weeks early. She's in a real fight. 🙏🏻 @ufc
