Jazz center Al Jefferson will have an MRI on his sore ankle and leg Thursday, coach Tyrone Corbin said before practice.
Jefferson, Utah's top scorer and rebounder, did not play in Wednesday night's 111-106 double overtime loss to Toronto.
Jefferson started to participate in the Jazz's morning shootaround when he began to experience pain in his ankle and up into his leg. He left the shootaround about 10 minutes early, in the company of trainer Gary Briggs, and was declared out of the Toronto game about 90 minutes before tip-off.
Meanwhile, guard Raja Bell missed practice because of a sore knee and back, which he tweaked against the Raptors.
The Jazz say Jefferson and Bell will travel to Dallas and their availablity for Friday night's contest against the Mavericks will be a game-time decision.
