A show spokesman said Wednesday representatives of the NFL star called late Tuesday to cancel his appearance for personal reasons. The daytime talk show host's interview with Vick was set to air Thursday, Feb. 24.
The interview was to cover Vick's time in prison, his work with the Humane Society and his return to the NFL.
Vick missed two seasons and served 18 months in federal prison for a dogfighting operation based on his property in Surry County, Va.
He was reinstated to the NFL for the 2009 season and has been doing public service work, including with the Humane Society.
