Shaquille O’Neal will star in a TV series where the NBA center will challenge top athletes such as Michael Phelps in their respective sports.

During one episode of “Shaq Vs.,” which debuts on Aug. 18 on ABC, Shaq will swim against Olympic superstar Phelps.

O’Neal, now with the Cleveland Cavaliers, also will try his football skills against Pittsburgh quarterback Ben Roethlisberger, box retired world champion Oscar De La Hoya, bat against St. Louis slugger Albert Pujols, trade tennis volleys with Wimbledon champ Serena Williams and play volleyball against Olympic gold medalists Kerri Walsh and Misty May-Treanor.

O’Neal will negotiate a handicap with his opponents and train with a coach for one week leading up to each challenge.

“These athletes may be on top of their game, but I am up for the challenge,” O’Neal said. “I plan to train hard and win, so look out.”

O’Neal came up with the idea for the competition as a way of training for the upcoming season.

His first opponent will be Roethlisberger, the Steelers’ Super Bowl-winning QB. They’ll compete in a 7-on-7 passing drill to be filmed later this week in the Pittsburgh area. Also, there will be a news conference leading up to the event as well as before future challenges.

A four-time NBA champion with the Los Angeles Lakers and Miami Heat, O’Neal was traded from Phoenix to Cleveland last month. The 37-year-old has just one season left on his contract but said he wants to play three more years and is hoping he can help Cleveland superstar LeBron James win his first league title.
