TAMPA, Fla. (AP) Cam Newton threw for two touchdowns and Josh Norman returned one of Carolina's four interceptions of Jameis Winston for his second TD of the season as the Panthers remained unbeaten with a 37-23 victory over the Tampa Bay Buccaneers on Sunday.

Newton tossed scoring passes of 6 and 12 yards to Ted Ginn Jr. A week after making a game-saving interception in the end zone against New Orleans, Norman scored on a 46-yard runback and later returned a another pick 34 yards to set up a second TD.

Tight end Ed Dickson rumbled 57 yards after recovering a fumble to score in the third quarter.
