John Wooden, who built one of the greatest dynasties in all of sports at UCLA and became one of the most revered coaches ever, died Friday night. He was 99.

The university said Wooden died Friday night of natural causes at Ronald Reagan UCLA Medical Center, where he had been hospitalized since May 26, according to an Associated Press report.

Hall of Fame coach John Wooden has been hospitalized with dehydration since May 26, UCLA officials said on Friday.

The school didn't address reports that Wooden is in grave condition.

Wooden, 99, led the Bruins to 10 NCAA championships.

Former UCLA basketball coach John Wooden has been hospitalized in Los Angeles, according to Bill Walton.

The former UCLA star said Thursday night that the 99-year-old Wooden was at UCLA Medical Center, where Walton last visited with him two days ago.

Walton spoke at the NBA finals, where he declined to comment on Wooden?s condition.

Los Angeles television station KCAL and the Los Angeles Times first reported that Wooden was in ?grave? condition.

Duke coach Mike Krzyzewski is flattered by the reports linking him to jobs in the NBA, but says he's not leaving the college ranks.

He admitted Wednesday that "it's more of a compliment -- it's not an insult," but reiterated what he says whenever rumors pop up: He's not leaving Duke.

"You just can't take it further than that, because then you're trying to milk the situation for the wrong thing," Krzyzewski said. "So I'd rather nip it right away and move on."

Krzyzewski's name has been linked to the Cavaliers this offseason. During the season, he saw his name mentioned as a possible candidate for the Nets as well.

"I never put my name in [for those jobs]. It's OK that someone mentions your name, and then it's OK for me to say that I'm not interested," Krzyzewski said. "It doesn't go any further than that. ... I haven't been offered anything, so when your name is mentioned, it doesn't mean that you've been offered anything. It's just, 'OK, why don't we say his name?' And who says it? So I'm very, very happy here at Duke."
