Despite news of Katherine Heigl’s supposed exit from the widely popular ABC drama, recent news has pointed to the actress’ staying on as Dr. Izzy Stevens, due to a contractual obligation she has for the series. earlier rumors pointed to a salary disagreement between Heigl and the TV network, but ABC recently released a statement Katherine has been given a “significant” salary increase due to “recognition of her tremendous talent and value to the show” and said that she will be staying on the show. Sources have cited Heigl feeling “less valued” by the network compared to her other co-stars like Sandra Oh and Isaiah Washington. ABC execs have pointed to a contract that binds Heigl to the show “for several years to come” and says that she will continue to reprise her role in the TV drama.
