SAN ANTONIO (AP) -- LaMarcus Aldridge had 21 points and 10 rebounds and the short-handed San Antonio Spurs beat the Chicago Bulls 133-94, setting a season-high in points despite missing a third of their roster Saturday night.
Chicago lost rookie forward Lauri Markkanen to a sprained left ankle late in the first half. The severity of the injury is unknown.
The Spurs were without six players, including three starters. In addition to Kawhi Leonard and Tony Parker, who have yet to play this season due to quadriceps injuries, San Antonio was also without Danny Green.
