With the emergence of QB Tony Romo in their road victory over the Panthers, the Cowboys flew to FedExField for a rematch with the Washington Redskins.  In the first quarter, Dallas trailed early as Redskins MLB Lemar Marshall tackled RB Julius Jones in the endzone for a safety and kicker Nick Novak kicked a 28-yard field goal.  In the second quarter, the Cowboys started to fight back, as Romo completed a 10-yard TD pass to WR Terry Glenn (with a failed two-point conversion) and kicker Mike Vanderjagt kicked a 33-yard field goal.  The 'Skins would retaliate as RB Clinton Portis ran 38 yards for a touchdown, yet Vanderjagt would allow Dallas to tie at halftime on a 30-yard field goal.  In the third quarter, the Cowboys increased their lead with Romo completing a 4-yard TD pass to WR Terrell Owens, who would do a "sleeping celebration." afterwards.  He would get flagged for excessive celebration. The "sleeping celebration" referenced Owens' admission earlier in the week that he has trouble staying awake during team meetings. In the fourth quarter, Washington fought back with QB Mark Brunell completing an 18-yard TD pass to TE Chris Cooley.  Afterwards, the Redskins would block a 35-yard field goal try by Vanderjagt, which would get picked up by Sean Taylor and returned it 30 yards before getting tackled.  Even though time ran out, the Redskins would get one chance to win, due to a face mask infraction penalty on Guard Kyle Kosier.  Washington took advantage, as Novak kicked the game-winning 47-yard field goal to drop Dallas to 4-4. Stats
