Justin Timberlake’s tenure as a “special correspondent” for ABC Sports officially starts tonight with ABC’s first NBA telecast of the year. “It’s a title that we gave for a position that we are still figuring out,” ABC Sports senior VP and executive producer Michael Pearl tells The New York Post. The *NSYNC star will file a number of short features from the perspective of a sports fan, according to Pearl. “He’s an average fan who happens to be a celebrity,” says Pearl. He is not expected to appear on the telecast tomorrow – and his first piece won’t be for at least several weeks.
