LOS ANGELES Jeff Conaways manager says the actor is in critical condition and facing a crucial period for survival.
The 60-year-old Conaway has been hospitalized since May 11, when he was found unconscious from what manager Phil Brock said was a drug overdose that may have involved pain pills.
Conaway, who starred in TVs Taxi and the movie musical Grease, has pneumonia and sepsis, a deadly blood poisoning caused by a bacterial infection. The next 48 hours are considered crucial. To aid his recovery, Conaway was in a medically induced coma at the Encino Tarzana Medical Center, Brock said.
In 2008, the actor aired his battle with addiction on TVs Celebrity Rehab. Conaway has struggled with back pain and repeated operations, Brock said.
