The Saints look to improve to 5-0 with Teddy Bridgewater as their starter in Brees' place when they visit Khalil Mack and the Chicago Bears on Sunday.

The Saints (5-1) are getting big contributions from their defense and special teams and enough from their offense even if they're not moving the ball the way they did a year ago. They're averaging 344.7 yards - down 34.5 yards per game from last season, when Brees made 15 starts. He's been sidelined since he tore a ligament in his right thumb during a loss to the Los Angeles Rams in Week 2.

Bridgewater has completed about 69 percent of his passes for 1,089 yards, seven touchdowns and two interceptions. He wasn't as effective last week at Jacksonville, after throwing for 314 yards and four touchdowns against Tampa Bay, but he hit Jared Cook for a tiebreaking 4-yard TD early in the fourth quarter against the Jaguars.

He will try to keep the Saints rolling against a team looking to bounce back. The Bears (3-2) are coming off a loss to Oakland in London two weeks ago in which their defense got pushed around a bit after dominating the first four games and their offense continued to struggle.

The Bears hope to get quarterback Mitchell Trubisky back after missing a game because of a left shoulder injury.

If he returns, he'll try to build on a promising showing against Washington in Week 3.

Trubisky threw three touchdowns in an easy win over the struggling Redskins after mediocre outings in a season-opening loss to Green Bay and a narrow victory at Denver. He was then injured on the opening drive against Minnesota on Sept. 29.

Veteran Chase Daniel figures to make his second straight start if Trubisky is unavailable.

With 18 sacks, New Orleans is tied with Green Bay and Tennessee for sixth in the NFL.
