Wilbon undergoes angioplasty after minor blockage discovered

Michael Wilbon, who co-hosts ESPN's "Pardon the Interruption" and writes a column for The Washington Post, remained hospitalized Tuesday, a day after undergoing an angioplasty in Scottsdale, Ariz.

Wilbon was taken to a Scottsdale-area hospital early Monday morning. Doctors found a minor blockage in one of his arteries and performed the angioplasty.

He is expected to leave the hospital soon, possibly as early as Wednesday.

Wilbon missed the airing of Monday's episode of "PTI" and was replaced by ESPN.com's J.A. Adande, who co-hosted with Tony Kornheiser via satellite from San Francisco. A possible date for Wilbon's return to the show is unknown.
