Poueu, who lost 142 pounds on the show, fell several stories. He is being treated at a San Francisco hospital for a punctured lung, a broken leg, torn ligaments and a pelvic injury.

His season nine castmate Ashley Johnson said on Facebook:

    "Sam Poueu is making great improvements everyday. God is answering our prayers and Sam is fighting. Please keep the prayers coming. He is still in critical condition, but is fighting like hell and is impressing the Doctors like he impressed all of us"

Our well wishes go out to Sam and his family! He announced his engagement to fellow contestant Stephanie Anderson last year.
