(The Sports Xchange) - Los Angeles Clippers forward Blake Griffin missed Sunday's game against the Oklahoma City Thunder due to a staph infection in his right elbow and will have surgery Monday in Los Angeles.
Griffin is expected to miss four to six weeks, but Clippers coach Doc Rivers said there is no timetable for his return. Griffin will be re-evaluated after the All-Star break.
Griffin is averaging 22.5 points, 7.5 rebounds and 5.1 assists this season.
Portland Trail Blazers guard Damian Lillard has been named to replace Griffin.
Lillard, who will appear in his second All-Star game, ranks 13th in the NBA in scoring (21.6 points per game) and 15th in assists (6.3).
New Orleans Pelicans All-Star forward Anthony Davis was diagnosed with a right shoulder sprain, an injury that forced Davis to leave Saturday's game against the Chicago Bulls.
Davis is questionable for Monday's game against the Utah Jazz and is listed as day-to-day.
He is scheduled to be a starter in next Sunday's NBA All-Star Game, and it remains unclear whether he will play.
Davis is averaging 24.5 points, 10.3 rebounds and 2.7 blocks this season.
The Memphis Grizzlies recalled guard Jordan Adams from the Iowa Energy of the NBA Development League.
