Roberts, the team's starting point guard, was ruled out with a left knee bone bruise. Gordon was sidelined for the second consecutive game with tendonitis in his left knee. Rivers has an upper respiratory infection.

“We don't want to rush (Roberts),” Pelicans coach Monty Williams said. “He has a bone bruise, so that can take a day or two to calm down. We don't know. He also has a bit of a calf strain.”

With Roberts the starting point guard and Rivers the backup, guard/forward Tyreke Evans started at point guard Wednesday. He played there during his his first season in the NBA with the Sacramento Kings, when he was chosen Rookie of the Year.

Anthony Morrow started at shooting guard in place of Gordon, and Al-Farouq Aminu started at small forward in place of Evans.

Roberts was injured Monday when he was fouled by Brooklyn Nets forward Mirza Teletovic at 5:23 of the fourth quarter while driving to the basket. He lay on the court for several minutes but got up, made the two free throws and played the rest of the game in the overtime victory.

This marks Gordon's third consecutive missed game. He came out during the first quarter of Friday's victory at Atlanta, did not return and hasn't played since. He then missed Saturday's big home win against Miami and the Nets game.

Like Roberts, Gordon's status is day-to-day. He said Monday that he hoped to play against the Clippers, his former team and who sent him to New Orleans in the Chris Paul trade.

Rivers had an ailment that has sidelined Evans, Gordon and All-Star power forward Anthony Davis for one game each in the past two weeks.

“(Rivers) tried to go out there and do his pregame warmup (Wednesday) but he couldn't do it,” Williams said.

Rivers missed a chance to go against the team coached by his father, Glenn “Doc” Rivers. The two went to dinner Tuesday night.

“He was sick (Tuesday) night, and I forced him to come to dinner with me in hopes that he would get sicker, and it worked,” Doc Rivers said jokingly. “No, he was really sick.”

Roberts leads the NBA in free-throw shooting at 94.9 percent. He has shot 111-of-117 but needs 125 to qualify. Eleven games remain after Wednesday night.
