CHICAGO -- Mark Sanchez made a strong opening argument for the Denver Broncos' starting quarterback job, throwing for 99 yards and a touchdown in the first quarter, and the defending Super Bowl champions beat the Chicago Bears 22-0 in the preseason opener on Thursday night.

Sanchez came through with just the sort of performance he needed if he's going to beat out Trevor Siemian.

He completed 10 of 13 passes in the first quarter and led a game-opening 76-yard touchdown drive. He was intercepted by Jerrell Freeman on the Broncos' second possession.

But overall? Not bad.

Sanchez maintained his cool against Chicago's pressure and kept the opening drive going by completing three third-down passes -- including a 32-yard TD to a wide open Demaryius Thomas along the right side.

As for Siemian, the former Northwestern star looked comfortable throwing short passes and was 7 of 12 for 88 yards in the second quarter.

It was a rough start for a Bears team looking for more after going 6-10 in coach John Fox's first season.

Jay Cutler threw for 18 yards and got sacked twice in the first quarter. Brian Hoyer threw for 81 yards in the second period but was sacked three times.

On a positive note for the Bears, Alshon Jeffery played after being limited by a strained hamstring and caught a 12-yard pass. And Kevin White caught his first pass for Chicago after missing his rookie season because of a fractured shin (see full recap).

Schaub leads Falcons to win in return to Atlanta

ATLANTA -- Making a successful return to his first NFL home, Matt Schaub passed for 179 yards, leading three scoring drives, and the Atlanta Falcons beat the Washington Redskins 23-17 on Thursday night.

Schaub began his career with the Falcons as Michael Vick's backup from 2004-06. He played seven seasons as Houston's starter and the past two years with Baltimore and Oakland. Schaub, 35, played most of the first half and solidified his status as Matt Ryan's top backup.

After Ryan was 0 for 4 and could not manage a first down on two possessions, Schaub moved the offense by finding Aldrick Robinson for long passes of 47 and 68 yards. Schaub completed 10 of 15 passes for 179 yards, giving Atlanta a 13-3 halftime lead.

Falcons rookie J.D. McKissic returned a kickoff 101 yards for a touchdown to open the second half.

Redskins starter Kirk Cousins completed each of his five passes for 39 yards on his only possession. Colt McCoy played the remainder of the first half, completing 7 of 11 passes for 53 yards. McCoy led Washington to its only scoring drive of the half, a 41-yard field goal by Dustin Hopkins.

Atlanta led 23-3 before Washington third-string quarterback Nate Sudfeld led two touchdown drives (see full recap).

Ravens battle back to beat Newton, Panthers

BALTIMORE -- Cam Newton directed a 68-yard drive in his only series, then stepped aside as the Carolina Panthers lost to the Baltimore Ravens 22-19 on Thursday night in a preseason opener.

Newton, the reigning NFL MVP, went 5 for 6 for 36 yards before being replaced by 33-year-old Derek Anderson.

Graham Gano kicked four field goals for the Panthers, who went 15-1 last year and won the NFC championship before falling to Denver in the Super Bowl.

Baltimore was without quarterback Joe Flacco, who's coming off a season-ending knee injury. Running back Justin Forsett; wide receivers Steve Smith and Breshad Perriman; and linebackers Terrell Suggs and Elvis Dumervil were also held out of the game.

The Panthers launched their preseason with a crisp 14-play march overseen by Newton, who opted not to employ the running aspect of his game.

Working out of the no-huddle offense, Newton completed his first five passes before overthrowing an open Ted Ginn Jr. in the back of the end zone. That forced Carolina to settle for a field goal.

Anderson threw a TD pass to Devin Funchess for a 10-0 lead before the Ravens answered with touchdowns by Terrance West and Javorius Allen.

Ryan Mallett, who started the final two games for Baltimore last year, got the call in this one, too. He played the entire first half, going 11 for 15 for 91 yards and a score (see full recap).
