Jazz point guard Deron Williams didn't participate in a shootaround Monday morning because of a lingering stomach flu and was to be a game-time decision for Game 4 of the Western Conference finals.

The Jazz trail the Spurs 2-1 after a 109-83 victory Saturday night in which Williams scored 31 points. He is averaging 30.3 for the series.

Williams showed up at the team's practice gym Sunday complaining of stomach problems. He was given medicine and sent home. On Monday, Williams received treatment while his teammates practiced.
