DETROIT – Mitchell Trubisky's 3-yard touchdown pass to David Montgomery with 2:17 remaining in the game gave the Bears an exciting 24-20 comeback victory over the Lions on Thanksgiving in Detroit.

The TD capped a nine-play, 90-yard drive that was sustained by clutch Trubisky completions to Anthony Miller of 35 yards on third-and-four from the Bears' 16 and 32 yards on third-and-five from the Lions' 34.

With their second straight win and third in four games since a four-game losing streak, the Bears (6-6) reached the .500 mark.

The Bears clinched the win when Eddie Jackson intercepted a desperation David Blough pass at the Chicago 10 on fourth-and-22 with :29 left in the game.

On third-and-nine, Roquan Smith sacked Blough on a well-timed blitz up the middle for a 13-yard loss.

After several slow starts in recent games, the Bears finally got off to the fast start they were seeking Thursday against the Lions, scoring a touchdown on their first possession for the first time in eight contests.

Cordarrelle Patterson returned the opening kickoff 57 yards to the 50, and Trubisky followed by completing 4 of 4 passes for 31 yards, including a 12-yard touchdown strike to Allen Robinson II, giving the Bears a 7-0 lead. It was their first TD on an opening drive since Sept. 29 versus the Vikings.

The Lions followed by scoring 17 unanswered points, however, to take a 17-7 lead. Blough, an undrafted rookie who had never taken a snap in an NFL regular-season game, threw a 75-yard touchdown pass to a wide open Kenny Golladay on Detroit's third play from scrimmage.

There appeared to be a mix-up on the play by the Bears secondary. Cornerback Prince Amukamara seemingly passed off Golladay to a safety, but there was no second defender to pick up the Lions receiver. The TD electrified the Ford Field crowd and tied the game 7-7.

It was the first touchdown the Bears have allowed on an opponent's opening possession since Week 7 of last season against the Patriots, snapping what was the NFL's longest active streak at 21 games.

After the Bears went three-and-out, Blough capped a 10-play, 78-yard drive with an 8-yard touchdown pass to receiver Marvin Jones Jr., giving the Lions a 14-7 lead with 4:12 left in the first quarter. Jones was wide open running across the middle from right to left.

Lions fans chanted "MVP" after Blough had completed 4 of 6 passes for 131 yards and two TDs and a 149.3 passer rating on his first two NFL drives.

The Bears later put together a 15-play drive, marching from their own 9 to the Lions' 36. But penalties on Javon Wims for a block in the back and Rashaad Coward for a facemask resulted in first-and-32 from the Chicago 32.

Eventually faced with fourth-and-6 from the Lions' 32, the Bears passed up a 50-yard field-goal attempt and kept their offense on the field. After a timeout, Trubisky threw incomplete intended for Wims. But a first down would have been nullified anyway due to a penalty for an illegal formation on the play.

The Lions extended their lead to 17-7 on Matt Slater's 25-yard field goal with 3:10 left in the second quarter. The 11-play, 61-yard drive was highlighted by Blough's 34-yard pass to Golladay to the Bears' 14.

The Bears answered as Eddy Piñeiro's 30-yard field goal cut the deficit to 17-10 with :22 remaining in the first half. Trubisky completed 4 of 6 passes for 47 yards on the drive.

The Bears reached the Lions' 33 on their first possession of the second half before Trubisky's pass intended for Robinson was intercepted.

After the Bears defense delivered its second straight three-and-out of the second half, Trubisky redeemed himself by tossing an 18-yard touchdown pass to Jesper Horsted, tying the game 17-17 with 4:44 left in the third quarter. Trubisky completed 6 of 6 passes for 84 yards on the drive.

The Lions responded by taking a 20-17 lead on Prater's 24-yard field goal with 10:42 left in the fourth quarter. Detroit settled for the kick after Kyle Fuller stopped running back J.D. McKissic for no gain on third-and-one with a terrific shoe-string tackle in the open field.
