The Chicago Bears defense apparently still hasn't recovered from last week's botched Hail Mary.

The Bears' defense completely collapsed in the final seconds before halftime of their game against the Arizona Cardinals on Sunday afternoon, allowing a touchdown. With that, the Cardinals, who were well out of field goal range before the game was scored, went into the locker room with a 21-9 lead at State Farm Stadium.

Cardinals quarterback Kyler Murray handed the ball off to running back Emari Demercado on a third down with just 12 seconds left in the second quarter. They were still on their own side of the field and expected at most a long field goal attempt before halftime.

But somehow Demercado broke through the line and ran 53 yards, almost completely untouched, for a touchdown.

That was their second touchdown of the quarter, following a 1-yard touchdown run by Noah Swell less than three minutes earlier.

The blown play marked the second straight half in which the Bears stumbled. The Washington Commanders stunned the Bears last week with a last-second Hail Mary on a perfect throw from Jayden Daniels to Noah Brown. The play, which will go down as one of the best Hail Mary passes in modern NFL history, got even worse for Chicago after cornerback Tyrique Stevenson was seen taunting Commanders fans before completely letting his guard down .

As a result, Stevenson was also left out of the starting lineup on Sunday. He also reportedly didn't respond to the news long before the game, as he briefly withdrew from training on Wednesday to “compose himself.”

The Bears entered Sunday's game with a record of 4-3. If they had stopped the Hail Mary last week, they would have also gone on a four-game winning streak. Now, however, Matt Eberflus' defense appears to be struggling when it matters most.
