TV Guide reports that Sarah Wayne Callies will not be returning to Prison Break.

The mother-to-be was expected to return as Dr. Sara Tancredi for the third season of the FOX series, but that doesn't seem to be the case:

We already knew that Callies was MIA from the opening credits in the first two episodes and that, for the one scene in which Dr. Sara appeared, a body double was used. But nonetheless, trusting souls that we are, we believed the mom-to-be still had a job. Well, no more. There's a story here, and you're gonna get it.

The series returns with new episodes on September 17.
