Rebounding was one of the Kings' preseason concerns, and it remains problematic after eight games.
Sacramento has been outrebounded by 6.13 rebounds per game, the biggest deficit in the NBA entering Thursday.
The Kings (2-6) have been outrebounded in six games, and they've lost all six.
"Defensive rebounding has been a sore spot for our team, not just this year but the last couple of years," Kings coach Keith Smart said.
The Kings hope center DeMarcus Cousins' return tonight after a two-game suspension will help.
Cousins leads the Kings with 9.8 rebounds per game.
Smart wants players to hustle to the ball more.
"Rebounding not just in your area but rebounding out of your area," Smart said. "That's what we have to do to close that gap. Not leaking out to try and get out on the fast break before we secure the rebound."
Back together The Kings will have their full roster tonight against Atlanta.
Suspensions, illness, injuries and personal matters forced Smart to use makeshift lineups the past three games.
Guard Isaiah Thomas returned to practice Thursday after missing Tuesday's game against the Portland Trail Blazers and Wednesday's practice after the death of his grandmother.
Forward Francisco Garcia (flu) also practiced Thursday after missing Tuesday's game and Wednesday's practice.
Cousins missed Sunday's and Tuesday's games because of his suspension.
Guard Aaron Brooks (sore left ankle) was kept out of Tuesday's game after the first quarter by Smart but practiced Wednesday and Thursday.
Bench points Even with the lineup changes, the Kings have received scoring help from their reserves.
Sacramento's bench has outscored opposing reserves 84-41 the past two games and by an average of 37.4-29.6 this season.
