After a spectacular offensive performance all around by the Saints against the 49ers, they headed to Dallas to face off against their NFC rivals the Cowboys. The Cowboys started off strong with a 77-yard Julius Jones run, but they were silent for the rest of the quarter.  In the second quarter, a shaky Saints team suddenly scored on all three of their drives: a 2-yard run from Mike Karney, a 3-yard pass from Drew Brees to Karney, and a 27-yard pass from Brees to WR Jamal Jones; and to cap it all off, Dallas kicker Martin Gramatica missed a field goal at the end of the half.  A surprising Saints team stymied the Cowboys to a field goal by Gramatica, and Reggie Bush quickly answered with a 61-yard catch for a touchdown.  Terrell Owens answered with a 34-yard touchdown catch. Mike Karney struck again with a 6-yard catch, and after a challenge by Sean Payton it was ruled a touchdown.  The Saints recovered an onside kick at the 40, and Devery Henderson caught a 42-yard pass and crawled in for a touchdown. With the blowout against the Cowboys, the Saints improved to 9-4 and are one game away from clinching the NFC South. Mike Karney was called by Drew Brees 'Mr. Touchdown,' because he had three touchdowns.. How many touchdowns longer than 40 yards were scored in the second half?
