The "Birdman" is missing for Denver.
Chris Andersen was on the court for pregame introductions before Game 4 of the Western Conference semifinals Monday night in Dallas, but the Nuggets' 6-foot-10 post player then went back to the locker room because of some kind of stomach bug.
Andersen wasn't seen on the Denver bench after the start of the game.
In Game 3 on Saturday, Anderson fouled out in only 11 minutes. He had eight points and nine rebounds while playing 25 minutes in Game 2.
