GLENDALE, Ariz. — The play call was a simple run, designed to gain 5 or 6 yards as the Arizona Cardinals maneuvered into position for a potential long field goal at the end of the first half.
Emari Demercado had other ideas.
The third-string running back dashed for a game-changing 53-yard touchdown, James Conner added 107 yards on the ground and the surging Cardinals put together a dominant 29-9 victory over the Chicago Bears on Sunday.
''That was a huge swing for us, him ripping off a 50-plus touchdown run right before halftime,'' Conner said. ''He's so smooth and fluid with it. That's one of his plays. He just put his foot down.''
The Cardinals (5-4) have won three in a row for the first time in three seasons.
It's another tough loss for the Bears (4-4), who have dropped two straight. They lost to Washington 18-15 last week on a Hail Mary and were burned once again as the clock was winding down against the Cardinals, though this lapse came in the final seconds of the first half.
Chicago rookie quarterback Caleb Williams was sacked six times, completing 22 of 41 passes for 217 yards. The Bears had just 241 yards total. Williams limped off the field late in the game with an ankle injury, though coach Matt Eberflus and the quarterback didn't believe it was a serious problem.
Demercado stunning score with four seconds remaining gave Arizona a 21-9 halftime lead. The Cardinals started the drive with 26 seconds remaining following Chicago's field goal.
