"He'll be evaluated day-to-day and when it resolves he'll be ready to play again," Carlisle said. "But, there is no timetable."
Wright will not be allowed to play until all concussion-like symptoms are non-existent.
Wright sustained the injury during Friday's game at New Orleans, possibly in the first half when he got hit in the mouth and had to leave with a bloody mouth. He did play later in the game, including in the fourth quarter.
After the game, the Mavs' medical staff administered a concussion test.
His absence comes at a bad time against Utah's strong front line. Ian Mahinmi, whose minutes have dwindled over the past few weeks will be the lone center backing up Brendan Haywood, who played Friday night despite having a troublesome back.
