Echemandu nicked

Running back Adimchinobi Echemandu underwent an MRI Monday to determine the severity of his hamstring injury. Echemandu suffered the injury on his first carry during Sunday's loss to the Chargers, though he finished the game with 62 yards on 10 carries. The Texans are unsure if he will be limited this week, according to the Houston Chronicle. Echemandu provide the moribund Texans running game with the first bit of life they've seen in weeks; with Ahman Green continuing to nurse a knee injury and Ron Dayne being, well, Ron Dayne, a healthy Echemandu could be the Texans' go-to back down the stretch.
