When Nurse Jackie returns for its second season, Nurse Mohammed "Mo-Mo" De La Cruz will not be checking back in to All Saints Hospital.

's abrupt exit from the show, which was first reported in late December, is a result of how another character — Eve Best's Dr. O'Hara — developed, according to executive producer Linda Wallem.

Wallem says O'Hara didn't exist in the original pilot, and when they added the sassy doctor character, Mo-Mo had less to do. "We love Haaz; we miss him," Wallem said. "[The character] did not sustain what we wanted to do because O'Hara took over the best friend role."

Nurse Jackie
returns for its second season on March 22 at 10/9c on Showtime.
