Britt said he was sending a message to teammate Vince Young, who's on season-ending injured reserve. Britt took the towel off at halftime.
"I just wanted to put the message out there," Britt said. "But it was against the rules. I did it, and I have to take it like a man.
"Everybody has their own opinion about why I did it, but that's my big brother and I am going to support him regardless," Britt said. "No one in here wants to win a Super Bowl more than Vince. For his year to end with an injury, it hurts me more than anything. I am going to support him. He can't play, so I am going to go out there and show my support for him. I am going to play the rest of my season for him."
