Banged-up Cardinals draw Panthers with backup QB

The Arizona Cardinals have been good in many areas. Some of those are categories where the Carolina Panthers are falling short.So, this upcoming matchup looks like an uphill battle for the Panthers when the teams meet Sunday in Glendale, Ariz.Yet there’s a strange similarity as the team’s prepare for this game — both teams have concerns at quarterback.”It’s a battle of attrition once you hit the second part of the season,” Cardinals coach Kliff Kingsbury said.So much so that Kingsbury opted for a walk-through over a full-fledged practice Wednesday given that 12 players were listed as non-participants.The Cardinals (8-1) have the NFL’s best record despite playing last week without Kyler Murray, who has an ankle injury.The Panthers (4-5), who’ve lost five of their last six games, need to sort out their quarterback situation, further complicated by an injury to erratic Sam Darnold’s right shoulder that will keep him out of action for at least a month, coach Matt Rhule said.Carolina acquired Matt Barkley off the Tennessee Titans practice squad, but it’s unclear if he’ll be a solution. P.J. Walker, who was used in last month’s road loss to the New York Giants, will get the start in Arizona.”I think all of us believe in P.J.,” Rhule said.The Panthers’ problems are widespread on offense, losing center Matt Paradis with a torn knee ligament in last week’s setback to New England. They’ve scored just one touchdown across the past three games combined, though they happened to win once during that stretch.”We’re going to stay together,” Panthers linebacker Shaq Thompson said. “We’re in this together. … We’re going to get this thing going and rocking.”Arizona has given up 17.3 points per game, reflecting the third-best mark in the NFL.The Cardinals rely on offense and they’ve generally been productive. They’ve had an NFL-high six games this season with 30 or more points.Murray has thrown for 17 touchdowns and seven interceptions in eight games. Colt McCoy filled in for last week’s 31-17 victory at San Francisco.”They’re explosive,” Thompson said. “Kyler makes that offense go.”The Cardinals would like Murray at the controls as he guided the season-opening seven-game winning streak.
