Marvin Lewis has banned the Bengals from using Twitter during training camp this summer. The coach is trying to get his players to focus while they work out at their downtown facility the next few weeks. "I don't think it's something where we're trying to fine guys $10,000 if they Twitter something," said offensive tackle Andrew Whitworth, who doesn't have a Twitter account. "I think we're just more saying, 'Let's let our focus be on what we do.'"
