"As a part-time comedian I realize that my words and actions are sometimes inappropriate," Harkaway said in a statement to Philly.com issued by a personal representative. "In this instance, after standing up to boo and being provoked by Russell Westbrook calling attention to my being overweight, my action in response was clearly inexcusable and I am embarrassed. I sincerely apologize to my fellow Sixers fans, the Sixers organization, my colleagues and patients, and to Mr. Westbrook for my behavior."
