CHARLOTTE, North Carolina (AP) -- Graham Gano kicked a 52-yard field goal in overtime to lift the Carolina Panthers to a 29-26 win over the Indianapolis Colts on Monday to remain one of four unbeaten teams in the NFL.
After Andrew Luck rallied the Colts from 17 points down in the final 7 1/2 minutes of regulation, both teams exchanged field goals in overtime.
Roman Harper then deflected Luck's pass over the middle to Coby Fleener and Luke Kuechly -- who had dropped an earlier interception that would have sealed the game at the end of regulation -- came up with the pick at the Colts 39.
Four plays later, Gano hit the winner to extend the Panthers regular-season winning streak to 11 games, dating to last season.
Cam Newton was 16 of 35 for 248 yards with two touchdowns and one interception. He also ran for 41 yards.
Luck had been limited to 40 yards passing and two interceptions through the first three quarters, but caught fire in the fourth quarter. He threw an 18-yard touchdown pass to Andre Johnson and an 8-yard TD strike to Fleener to bring the Colts to within the 23-20.
Adam Vinatieri hit the third of his four field goals as time expired to send the game into overtime. He then gave the Colts a 26-23 lead on a 50-yarder with 12:04 left in the extra period.
In a bizarre incident in the second half, two activists rappelled on ropes from the upper deck holding a banner protesting Charlotte-based Bank of America's role in financing a liquefied natural gas export facility in the state of Maryland.
The protesters dangled by ropes well into the fourth quarter before finally descending and being arrested by police.
