Biggest Loser alum Daniel Wright passed away Sunday following a nearly two year-long battle with Leukemia. He was 30. Fellow contestants confirmed the devastating news to social media Monday.

"I am so so heartbroken to hear about Daniel Wright this morning," Courtney Crozier Respess wrote on Facebook. She appeared on season 11 of the NBC weight-loss show and was a personal friend of Wright's. "He has fought SO HARD during his battle with cancer & more. This man is one of the kindest people I have ever met & is a true difference maker in this world!"

According to his Go Fund Me page, Wright, who competed on season 7 and season 8, was diagnosed in October 2017. Despite entering remission, he relapsed in December 2018 and his condition quickly worsened. "Within 24 hours of the relapse, Daniel was taken by ambulance to Iowa City about 2 hours from their home," an update reads. "Daniel and [his wife] Rebecca have spent the last 3 1/2 weeks in the hospital dealing with fever, infection, low blood counts, [and] chemo side effects."

His wife and fellow Biggest Loser contestant, Rebecca Meyer Wright updated family, friends, and fans on Daniel's condition via Facebook. In her most recent note, posted May 24, she detailed recent complications. A Procedure was reportedly scheduled to find the source of blood in his urine and vomit.

"Yesterday, the Lord broke me down & today because of your prayers & my pleading our Lord has made me warrior strong!!" she wrote. "I will let you know when they will be doing the procedure as soon as I know. He is much more alert today but still quite foggy… Man alive this is insane & alone seems impossible but with GOD all things are possible."

Sadly, he lost his battle with cancer two days later.

Season 8 winner Danny Cahill also posted an emotional tribute. "After a long heroic fight, my fellow Biggest Loser and Browns fan Daniel Wright is at peace now in our Lord and Saviors arms," he wrote. "I love you Daniel, I love you Rebecca, and I pray for your peace in this time of loss."
