Cardinals coach Bruce Arians and wide receiver Larry Fitzgerald are both confident Drew Stanton can help them win games after quarterback Carson Palmer suffered a broken left arm that will keep him out at least eight weeks. Palmer suffered the injury in the second quarter of Arizona's embarrassing 33-0 defeat to the Rams at Twickenham Stadium on Sunday. With the 37-year-old quarterback set to undergo surgery on the injury, the Cardinals will now turn to Stanton, who completed just 5 of his 14 pass attempts and threw an interception in relief of Palmer. Stanton did start eight games in 2014 after Palmer sustained an injury, throwing for 1,711 yards and seven touchdowns with five interceptions, and posting a 5-3 record. Speaking in the post-game media conference, Arians said: "Carson will have surgery. He'll have surgery on his arm when we get back and probably eight weeks, or the season. We don't know yet. "We played with Drew before," Arians added. "Drew has played and won a lot of games for us. He and Blaine [Gabbert] step up and take over the quarterback job."
