CHARLOTTE — Cam Newton threw for 263 yards and two touchdowns and ran for another score, and the Carolina Panthers defeated Tampa Bay 27-6 Sunday for a franchise-record eighth straight regular-season victory.

Newton threw touchdown passes to Brandon LaFell and Ted Ginn Jr. and “Superman” leaped over the pile for another score as the Panthers (9-3) outgained the Buccaneers 426-206.

The Carolina victory sets up a huge showdown next Sunday night with New Orleans with first place in the NFC South on the line.

Newton ran for 68 yards and overcame two interceptions. The third-year quarterback has thrown 13 touchdown passes and run for five scores during the Panthers’ current win streak.

Carolina’s defense, which came in allowing the fewest points in the league, forced two turnovers and sacked rookie Mike Glennon four times to snap a three-game winning streak for Tampa Bay (3-9).
