Representatives of Michael Vick called late Tuesday to cancel his appearance on 'The Oprah Winfrey Show' for personal reasons. The daytime talk show host's interview with Vick was set to air Thursday, Feb. 24. The interview was supposed to cover Vick's time in prison, his work with the Humane Society and his return to the NFL. "After careful consideration, I will need to postpone the taping of the Oprah Winfrey interview scheduled for February 22," Vick said in a statement. "I admire and respect Oprah and hope to be able to participate in an interview in the future."
