Hoping to continue building off of their two-game win streak, the Raiders flew to Qwest Field for a Monday Night showdown with the Seattle Seahawks.  In the first quarter, Oakland's woes continued to haunt them as QB Seneca Wallace completed a 22-yard TD pass to WR Deion Branch and kicker Josh Brown kicked a 20-yard field goal.  In the second quarter, Brown continued to make the Raiders visit terrible with a 25-yard field goal for the only score of the period.  After a scoreless third quarter, Brown would put the game away with another 20-yard field goal. This game marked the first time in Monday Night Football history that a team got shut out twice in one year.  Also, QB Andrew Walter got sacked 9 times and Oakland's overall offense was just 185 yards.
Question: How many more yards was the TD pass scored by Wallace versus Brown's field goal?
