Monday Night Football

Alex Smith completed 18 of 19 pass attempts for 232 yards and three touchdowns, and the San Francisco 49ers beat the Arizona Cardinals, 24-3, in Arizona on Monday night. San Francisco (6-2) led 17-0 at halftime on the strength of two scoring passes from Smith to Michael Crabtree. Smith connected with Randy Moss on a 47-yard touchdown midway through the third quarter. The 49ers coasted the rest of the way, allowing Arizona (4-4) just a 28-yard Jay Feely field goal prior to the start of the fourth quarter.

Brian Urlacher and D.J. Moore each collected turnovers to stifle potential second-half touchdown drives, and the Chicago Bears beat the Detroit Lions, 13-7, in Chicago on Monday night. It was the fourth straight win for Chicago (5-1). The Bears led 13-0 when the Lions threatened in the third quarter, advancing the ball to the 1-yard line before Urlacher recovered a fumble by Joique Bell of Detroit (2-4). Quarterback Matthew Stafford drove the Lions back into the red zone three possessions later, only to have Moore intercept his pass from the 3-yard-line.

Arian Foster ran for 152 yards and a touchdown, and the Houston Texans beat the New York Jets, 23-17, in East Rutherford, N.J. on Monday night. Kareem Jackson intercepted Jets' quarterback Mark Sanchez with 1:51 left to preserve the victory for Houston (5-0). The Texans and the Atlanta Falcons are the NFL's only remaining unbeaten teams.

Matt Ryan passed for 219 yards and two touchdowns, as the Atlanta Falcons took advantage of three first-quarter interceptions by Peyton Manning to beat the Denver Broncos, 27-21, in the Georgia Dome on Monday night.
