Jazz center Al Jefferson has tendinitis in his right ankle, an MRI examination revealed Thursday.

Utah's leading scorer and rebounder, Jefferson accompanied the team to Dallas, where the Jazz play Friday night. His availability against the Mavericks will be a game-time decision, a team spokesman said.

Coach Tyrone Corbin said Jefferson was fine during two days of practice early this week, but he left a Wednesday morning shootaround early because "he started to run and said he felt some pain running up his leg."

After being the only member of the Jazz to play in all 82 games last season, Jefferson did not dress for Toronto's 111-106 double-overtime win over Utah.

Meanwhile, veteran guard Raja Bell is listed as a game-time decision against Dallas because of soreness in his knee and back.
