Tony Romo has vowed to go without a haircut until the Cowboys lose again. Just in case their four-game winning streak increases significantly, Romo has gotten advice from linebacker Bobby Carpenter on tying a ponytail. "It will be a good problem to have if it gets too long," Romo said. "It's just something I said and someone is holding me to it." Asked if that someone were in the locker room, Romo said, "No."
