‘I’m back!’ Cam Newton helps Panthers stun Cardinals

Cam Newton ran for a touchdown and threw for a score in his first game back with Carolina as the Panthers stunned the Arizona Cardinals 34-10 Sunday at Glendale, Ariz.Starting quarterback P.J. Walker did much of the work for Carolina in the upset.The Cardinals (8-2) had the best record in the league and one of the top defenses, but the Panthers scored 17 first-quarter points and were in control throughout the game.Walker finished 22-for-29 for 167 yards, with an interception. Newton, who gained 14 yards on three carries, was 3-for-4 passing for 8 yards. Christian McCaffrey gained 95 rushing yards and 66 receiving yards for the Panthers (5-5).Arizona, using backup quarterback Colt McCoy because of Kyler Murray’s ankle injury, was held to 169 yards of total offense. McCoy was 11-for-20 for 107 yards with an interception before leaving in the third quarter with an upper-body injury.Newton signed with Carolina, which had made him the top pick in the 2011 NFL Draft, late in the week as a free agent. He was the 2015 NFL Most Valuable Player with the Panthers before spending last season with the New England Patriots.It seemed unlikely he would play with such a short preparation window as the Panthers sought to bolster the quarterback position. Starter Sam Darnold is out with a shoulder injury. Instead, Newton scored the game’s first points on a 2-yard run with 11:12 left in the first quarter.He took off his helmet and screamed, “I’m back!”
