The Chicago Bears suffered a 17-24 loss to the Carolina Panthers in the Bears' preseason opener Friday.


The defense picked up where they left off in 2012-13 and forced three first-half turnovers, one being a 51-yard interception for a touchdown by the Bears' 2013 second-round pick Jonathan Bostic. Bostic made a quick move for the ball and stole one from third-year quarterback Cam Newton.


"Really, I was just a spy underneath, so I was reading Cam's eyes," Bostic said. "I thought he was going to go a little bit more outside, and I jumped back at the last second when I saw him come back inside, and I happened to be in the right place."


All would not be smooth for the Bears. Jay Cutler's first throw from the line of scrimmage featuring new coach Marc Trestman's offense was an interception to Panthers cornerback Josh Norman. Chicago's offense stalled multiple times and were forced into three turnovers and allowed seven sacks. 


"You obviously don't want to see [an interception] on the first play of the game, but I loved [Cutler's] demeanor," Trestman said. "I thought he was calm and went right back at it." 


Cutler would eventually regain composure and complete 6 of his next 7 passes for 56 yards. 


The only Bears lead was generated by Robbie Gould's 35-yard field goal in the second quarter. After scoring two more touchdowns, the Panthers would only allow 7 more points and cement their victory, spoiling Trestman's coaching debut.
