David Beckham has refused to participate in Shaquille O”Neal’s upcoming ABC show ‘Shaq Vs.’.

The former England captain was approached for the show in which he had to compete against other pro athletes in their sports.

“Michael Phelps, Serena Williams and Steelers QB Ben Roethlisberger all signed on, but Beckham refused,” the New York Post quoted a source as saying.

O”Neal even called Beckham out on Twitter, saying: “Official, today is David Beckham is scared of shaq day, he should b scared, he can never score a goal on me.”

However, Beckham could not be contacted for a comment.
