"Chris Johnson got off to a good start against the Steelers — the fourth-year pro gained 21 yards the first time he touched the ball — but he limped to the finish.

Johnson said his hamstring felt tight in the fourth quarter, so he stayed on the sideline. The injury does not appear to be significant, however. "I was set to go back in," he said, "but they didn't want to injure it more knowing that the game was pretty much out of hand.""
