After missing the first four games of the season with a foot injury, Childress returned to the court on October 23 against the Adelaide 36ers. However, in his return game, he sustained another injury, this time breaking his right hand. He played through the Kings' 91–80 loss to the 36ers with the break and still managed to score 23 points, but following the game, he was ruled out for a further four to six games with a boxer's fracture.
