Phoenix Suns guard Devin Booker (back) has been officially ruled out on Tuesday.
Booker was considered unlikely to play after suffering a back injury late in Sunday's game. He is considered day-to-day with the injury. Josh Jackson is expected to start in his place against the Sacramento Kings with T.J. Warren seeing an increase in scoring responsibility.
Booker has averaged 24.8 points, 6.9 assists, and 39.6 FanDuel points per game this season.
