Watch: Shaq takes handoff from Tebow, bowls over Barkley

What You Need to Know: Shaquille O’Neal

Charles Barkley has tangled with Shaquille O’Neal during his pro basketball career, but the former NBA star wanted nothing to do with Shaq in a football situation.

During a segment of “NBA on TNT,” 2007 Heisman Trophy winner Tim Tebow dropped into the studio and ran a few plays with Barkley and O’Neal. When the former quarterback handed off to O’Neal, Shaq made a beeline for Barkley and knocked him off balance.

When O’Neal challenged Barkley to tackle him, but Barkley demurred, saying he hurt his shoulder.

When Barkley switched to offense, he also avoided O’Neal, who was intent on delivering a hard hit.
