Basketball Hall of Famer Bill Russell was released from the hospital Saturday after an overnight stay for an unspecified reason, he confirmed on Twitter.

According to TMZ, Russell, 84, reportedly was taken by ambulance from his home in the Seattle area to a nearby hospital. A representative for Russell told TMZ on Saturday that it was due to dehydration.

Russell later posted a follow-up tweet that included a photo of him holding a glass of water. He indicated that he was OK and ready for Game 3 of the Eastern Conference finals.

Boston Celtics coach Brad Stevens was relieved to hear that Russell was all right.

"Yeah, that was obviously scary news, and happy to hear that he's doing better and he's been released from the hospital,'' Stevens said in Cleveland before Game 3 against the Cavaliers. "He's the ultimate basketball winner. The way he impacted winning, the unselfishness of a teammate, what he stood for off the floor -- everything about him. It's an honor to get a chance to work for the Celtics.

"Those teams and those people from those teams -- and obviously Bill Russell being one of those main people in Celtics history -- are why it's an honor to work for them because of the bar they set for all of us.''

Russell was inducted into the Basketball Hall of Fame in 1975, was an 11-time NBA champion with the Celtics and won five NBA MVP awards.
