Krayzie Bone

Krayzie Bone, of Bone Thugs-N-Harmony, has been forced to postpone his current tour through Canada, after coming down with pneumonia.

According to TMZ, the rapper suffers from from sarcoidosis, an autoimmune disease that attacks the lungs, and came down with an intense case of pneumonia during his Canadian tour because his meds weaken his immune system.

Taking the advice of his doctors, Krayzie immediately cancelled his remaining tour dates and has traveled back to Los Angeles for treatment.

He plans to reschedule missed tour dates when he recovers.
