Davis was ruled out of the lineup about an hour before tipoff after receiving pregame treatment to see if he would feel well enough to play.
Lakers coach Frank Vogel said Davis woke up with the soreness on Friday and was unsure what caused it. Vogel didn't have an update on Davis after Friday's game.
Dwight Howard started in Davis' place and had one point and eight rebounds in 17 minutes.
Friday night marked just the second game Davis missed this season after being out 36 of L.A.'s 72 games last year because of various injuries.
The Lakers' next game is Sunday at home against the Orlando Magic.
