It didn't take long for the boos to rain down from Soldier Field.
The Bears went into halftime trailing by just two points, but wound up turning the ball over three times in a 14-minute span, handing the Philadelphia Eagles a 29-14 win in the Chicago home opener.
Jay Cutler was responsible for two of those turnovers, losing a fumble on a sack on the Bears' first drive of the second half and then throwing an interception in the shadow of his own endzone.
The pick was Cutler's last play of the night as he entered the locker room with a hand injury.
The Eagles, meanwhile, shot themselves in the foot with a couple of ill-timed penalities and drops early as rookie quarterback Carson Wentz looked impressive, but Philadelphia had to settle for field goals early.
Once the Bears offense started getting sloppy with the ball, the Eagles took advantage, scoring touchdowns on each of the three ensuing possessions.
The Bears defense looked as if they provided a spark, stuffing the Eagles at the goal line on a fourth-down attempt in the fourth quarter, but Leonard Floyd was lined up offside, giving the Eagles another chance, which they promptly converted to put the game well out of reach.
John Fox and the Bears coaching staff said they were going to commit to the running game this week, but the offense came out with only 10 yards on the ground on seven first-half carries.
The tide turned briefly in the second half with 51 rushing yards in the third quarter, including a couple of nice runs from Jeremy Langford and rookie Jordan Howard before Cutler's fumble.
The Bears suffered a slew of injures beyond Cutler, with Eddie Goldman, Adrian Amos, Bryce Callahan, Lamarr Houston and Ka'Deem Carey all leaving the game with ailments and not returning.
Before he left the game, Cutler was 12-of-17 for 157 yards and one interception.
In Cutler's place, Brian Hoyer completed 9 passes on 12 attempts for 78 yards.
Langford finished with the Bears' only offensive touchdown - a one-yard scamper in the second quarter. He tallied just 2.5 yards per carry (28 yards on 11 carries) on the evening and also lost a fumble.
Eddie Royal provided the second Bears score when he took a punt 65 yards to the house late in the fourth quarter when the game was already well in hand.
The Bears defense held the Eagles to less than 300 yards of offense (280) and did tally seven deflected passes coupled with a pair of sacks.
But the turnovers gave the Eagles short fields to work with and they capitalized to push their record to 2-0 while the Bears fall to 0-2 to begin the 2016 campaign.
