FOXBOROUGH, Mass. -- Texans starting cornerback Kevin Johnson suffered yet another concussion Sunday against the New England Patriots and was ruled out for the remainder of the game. This is a troubling recurrence for Johnson, who suffered a concussion during the preseason against the San Francisco 49ers and was cleared under the NFL concussion protocol Friday. Now, the former first-round draft pick from Wake Forest is back in the concussion protocol. "I'm feeling 100 percent," Johnson said Friday. "It feels real good to be cleared and to come out and play in this first game."
