It's been a bizarre pattern for Gasol, who missed a game against Golden State a little over a week ago because of the illness, then played two games and now will have missed the Lakers' last two games.
Lakers Coach Mike D'Antoni said he expected Gasol to play Tuesday against Milwaukee.
Chris Kaman took part in the team's shoot-around Sunday and was expected to play against Philadelphia despite sustaining a moderate sprain in his left ankle Friday when he stepped on a Utah player's foot.
The Lakers (13-17) are on a four-game losing streak. They are four games under .500 for the first time this season.
