Soap Opera actor Nathaniel Marston remains in critical condition following a car crash on Oct. 30, and he will “most likely live out his life as a quadriplegic,” his rep revealed to FOX411 on Wednesday.

“Marston underwent surgery November 4, and doctors were initially positive about the outcome. However, in the early morning hours of November 5 his heart stopped on two separate occasions requiring doctors to use an external pacemaker to regulate his heartbeat,” his rep stated in a press release. “He remains in critical condition, fighting pneumonia, a heart infection and irregular pulse.”
