Reddish won't play in Friday's game against the Suns for personal reasons, Ryan Ward of LakersNation.com reports.
Reddish wasn't previously listed on the injury report, so his absence comes as a surprise. The 25-year-old didn't leave the bench in the Lakers' 110-103 win over the Timberwolves in Tuesday's season opener, so he's not expected to be part of head coach JJ Redick's rotation once he rejoins the team.
