Newton aggravated a left mid-foot sprain during last Thursday night’s loss to the Tampa Bay Buccaneers and has not practiced since.
The former MVP has completed 50 of 89 passes for 572 yards with no touchdowns and one interception in the Panthers’ 0-2 start.
Allen, 23, started Carolina’s regular-season finale in 2018, completing 16 of 27 passes for 228 yards and two scores in a 33-14 win at New Orleans.
Allen, a native of Scottsdale, Ariz., would be starting in his own backyard against the Cardinals.
Allen and Arizona rookie quarterback Kyler Murray were teammates at Texas A&M in 2015. Allen won the Aggies’ starting job that year, but both players later transferred. Murray went on to win the Heisman Trophy at Oklahoma and Allen played four games at Houston.
Rookie Will Grier, a third-round pick from West Virginia, would back up Allen if Newton is unavailable.
