Kyrie Irving #11 of the Dallas Mavericks moves the ball down court against the Houston Rockets during the first half at Toyota Center on January 01, 2

Dallas guard Kyrie Irving is expected to miss one to two weeks with a bulging disc in his back, and Mavericks coach Jason Kidd said a timeline for his return was not immediately known.

Irving missed two of the Mavericks’ past three games. He sat out last Monday’s loss to the Kings with right shoulder soreness and Friday’s loss to Cleveland due to an illness. In 30 games this season, Irving has averaged 24.3 points, 4.9 assists and 4.6 rebounds.
