NFL: New Orleans 46, Miami 34

MIAMI, Oct. 25 (UPI) -- Interception returns for touchdowns by Darren Sharper and Tracy Porter highlighted a big comeback Sunday that gave New Orleans a 46-34 victory over Miami.

The Dolphins held a 21-point lead during the first half, were in front by 14 at the break and still owned a 10-point lead going into the fourth period.

New Orleans, however, outscored Miami 36-10 over the final two quarters and remained unbeaten in six games this season. The Saints, Denver and Indianapolis are the only teams in the NFL without a loss. Miami, which had won its previous two games, is 2-4.

Sharper began the second-half rally by picking off a Chad Henne pass and bringing it back 42 yards for a score.

Drew Brees hit Marques Colston with a 10-yard scoring throw in the third period, but the third touchdown run of the game by Miami's Ricky Williams helped the Dolphins take a 34-24 lead into the final period.

Brees then led the Saints 79 and 60 yards on consecutive possessions. Reggie Bush scored on a 10-yard run at the end of the first drive and Brees then put the Saints in front with a 2-yard touchdown blast -- his second of the day.

John Carney added a 20-yard field goal and Porter completed the surge with a 54-yard interception return for a score.

Brees was 22-of-38 for 298 yards and his three interceptions helped the Dolphins charge to their early lead. Henne was only 18-of-37 for 211 yards.
