An MRI showed no damage to Terrell Owens' left hamstring, but the new Dallas receiver still isn't ready to get back on the practice field. Owens missed his third consecutive day of work, this time sitting out an intrasquad scrimmage. He missed a morning walk-through to have the MRI. "I'm not worried at all," said Owens, who claims to have never had a hamstring problem before. "I know it'll get well. I know my body responds very quickly to treatment."
