One of the major figures of NBC’s “America’s Got Talent” will be out for quite some time. Iconic show judge Simon Cowell is expected to miss several weeks of “America’s Got Talent” while he undergoes a routine back procedure, according to reports from “TMZ.” Sources say there is “no indication of a new major health crisis,” with Cowell expected to temporarily step away from the NBC talent competition. No word yet on who will replace him for the time being.
