Ariza is starting Friday's game against the Clippers, Mike Trudell of the Lakers' official site reports.
Ariza came off the bench in each of the final two games prior to the All-Star break, but he'll rejoin the starting lineup while Stanley Johnson comes off the bench. Across eight starts this year, Ariza has averaged 3.0 points and 3.5 rebounds in 20.6 minutes per game.
