Dallas Mavericks star Kyrie Irving has a bulging disc in his back and is expected to miss at least one to two weeks, sources told ESPN.
There is optimism that treatment over the coming days will provide a return-to-play target date, sources said.
The Mavs announced on Sunday that Irving would miss Monday's game against the Memphis Grizzlies due to a lumbar sprain in his back. He did not join the team on the road trip, remaining in Dallas to be reevaluated, sources said.
Irving did not play in Friday's home loss to the Cleveland Cavaliers, when he was ruled out hours before tip-off due to an illness.
