He can only enter the game if both Murray and Wentz are unable to play because of an injury, illness or ejection.Why isn’t J.J. McCarthy playing?McCarthy lost the starting job to Murray during training camp and the preseason. Vikings coach Kevin O’Connell then chose the more experienced Wentz as the primary backup, leaving McCarthy as QB3 for Week 1.O’Connell has said the backup quarterback role could change from week to week.McCarthy also had an inconsistent 2025 season, throwing for around 1,632 yards, 11 touchdowns and 12 interceptions in 10 starts. Injuries also limited him during the season and preseason, although he returned to full practice before Week 1.Fans fume as Kyler Murray strugglesKyler Murray struggled early against the Packers, leaving Vikings fans calling for J.J. McCarthy to return to the starting role.One fan wrote on X, "JJ McCarthy has a higher completion rate then Kyler Murray as a Viking."Another added, "Kyler Murray proving he was the wrong choice to start for the Vikings.
