Noah Wyle may be hanging up his stethoscope on ER, but he’ll still be on call – for diaper duty.

The actor, 33, announced on The Tonight Show that he and wife Tracy are expecting their second child this fall.

The couple’s first child, a boy, was born on Nov. 9, 2002, and was named Owen Strausser Wyle – sharing the same middle name as his father.

As for Wyle’s role as Dr. John Carter on the NBC series, he will leave at the end of this season, though he will return for four episodes in each of the next two seasons. (The show has been renewed through the 2007-08 season.) Wyle is the only original star who has remained with the medical drama throughout its 11 years.

When the show premiered in September 1994, Dr. Carter was an impressionable young resident among a cast that included Anthony Edwards, George Clooney, Eriq La Salle, Julianna Margulies and Sherry Stringfield. As they departed, Wyle became the show’s focal point.
