When Lewis Travis unceremoniously headed the ball into his own net after eight minutes, you got the feeling it would be one of those days for Derby.   When The Rams skipper was given his marching orders in a fiery period of second half stoppage time, that feeling proved correct.   After the euphoric high of the 5-0 win at Bristol City, this unfortunate afternoon brought the Pride Park faithful back down to Earth. The play-off chase is on, but home form remains the barrier.
