It was a tragic low for an NBA star who once soared so high: Lamar Odom, former Los Angeles Laker, was carried unconscious from a brothel Tuesday afternoon. Authorities tried to fly him out — but, at 6-foot-10, he was too tall. And, as TMZ reported, he is now in a coma, his heart failing.

“It’s not good,” a source told TMZ.

The scene of Odom’s collapse — the cause of which is not yet known — was Dennis Hof’s Bunny Ranch in Crystal, Nev. Employees at the Bunny Ranch found Odom unconscious in his room with “mucus-type liquid coming out of his nose and mouth.” Hof, the brothel’s owner — featured in HBO’s documentary series “Cathouse” — told NBC News Odom was taking “herbal Viagra,” and “he was taking a lot of it.” The Mayo Clinic warns that products claiming to be natural forms of Viagra can cause dangerously low blood pressure.

“When we called 911, 911 said roll him on his left side,” Hof said. “And he started throwing up all kinds of stuff, foaming, throwing up all kinds of things. The girls said they didn’t see anything. The police came out and with the ambulance people. They didn’t see anything.”

He added: “The only thing we know for sure is that he was taking an excessive amount of herbal Viagra. Not to say that he wasn’t doing any drugs. But nobody saw anything like that. They saw no effects. What I understand is that he got a phone call and was a little bit somber on Sundayafternoon for a while. And then he kind of shook it off and was having a good time. … They were having a blast with Lamar.”
