Question: Is it 100 percent confirmed that Goran Visnjic won't come back (as a regular) for the 14th season of ER (Ask Ausiello 2/28)? What about Maura Tierney? Anything new on her coming back?

Answer: I'd say it's 99 percent certain he won't be back as a series regular. And Maura is contracted through next season, so she's definitely sticking around.
