Three hours after being an unwitting participant in a collision that resulted in a concussion, an unsightly taunting episode, and ample vitriol emanating from the visitors' locker room, Texans defensive tackle Travis Johnson was still seething. The elapsed time hadn't soothed Johnson's angst. He was unapologetic in his vulgar impressions of Miami Dolphins quarterback Trent Green, who lost consciousness when his helmet collided with Johnson's knee during a botched running play in the first quarter of the Texans' 22-19 victory on Sunday. Even after witnessing a motionless Green immobilized and transported to Methodist Hospital (Green returned to Reliant Stadium prior to the Dolphins' departure), Johnson was unabashedly furious afterward. "At 12:01, I had a lot of respect for Trent Green. At about 12:20, I said, '(Forget) Trent Green,' because the bottom line is it was a malicious hit," Johnson said. "It was uncalled for. He's like the scarecrow. He wanted to get courage while I wasn't looking and hit me in my knee instead of trying to hit me in my head." Given additional time to calm down, Johnson ? at the urging of Texans officials ? readdressed the incident and his reaction. Roughly 20 minutes after his initial tirade, Johnson showed contrition for his behavior and remorse for the fallout from his actions. "I apologize for going off like that," Johnson said. "As a D-lineman, when you have people going at your knees, it's tough on you mentally. But at the same time, I shouldn't have reacted like that. I'm sorry the penalty ended up leading to a score. ''I ended up hurting my team," Johnson said. ''I shouldn't have let my anger get to me. I apologized to coach Kub because I hurt my team. I should have kept my cool. But being in that situation, this is a game of controlled violence. Really, I let my anger get the best of me."
