ATLANTA -- Al Horford, the Atlanta Hawks' leading scorer and rebounder, is out indefinitely with a torn right pectoral muscle.
Horford left Thursday night's 127-125 double-overtime win at Cleveland in the first overtime with the injury and did not return. The Hawks say an MRI and examination on Friday by Dr. Michael Bernot in Atlanta revealed the complete tear of the muscle.
Hawks general manager Danny Ferry said the team will complete its "due diligence" to determine the next step for Horford.
Horford leads the team with 18.6 points and 8.4 rebounds per game.
Forward DeMarre Carroll is day to day with a sprained right thumb.
