Khan gets thumbs up from TV chief

Amir Khan's star potential in the US received a ringing endorsement last night from an influential American television executive. Britain's Khan made a big impression on his US debut at Madison Square Garden on Saturday, beating Paulie Malignaggi. "I thought that was a terrific performance from Amir," said Kery Davis, the senior vice president of sports programming at HBO, the leading boxing channel in America. "You could see his talent and his speed and his punching power." * Agencies
