Today on TV

The Superstars (7 p.m., Ch. 4): This dopey competition continues — and there's a major twist that seems almost too good to be true. (Not that I'm accusing anybody at ABC of trying to get better ratings or anything.) It seems that Jennifer Capriati injured herself competing in last week's episode, and she couldn't continue. So she and her teammate, David Charvet, are out. And, per the rules of this game, the last team eliminated — at this point, the only team eliminated — is back in the game. So Terrell Owens and "supermodel" Joanna Krupa return after the infamous meltdown in which Krupa proved herself to be the Wicked Witch of "Superstars." "This is a chance for us to redeem ourselves," T.O. says. And a chance for him and Krupa to create some more drama. Oh, and let's just say that while Capriati was the first participant to leave the competition because of an injury, she won't be the last to make an unscheduled exit.
