The injuries keep piling up for pass-rusher Khalil Mack, who missed Wednesday s practice with a shoulder problem. Mack sat out two days of practice last week because of a bad back and finished last Sunday s loss to the Detroit Lions with zero statistics. Mack has been a non-factor in several games this season as the Bears record plummeted from 5-1 to 5-7. The best guess is Mack still plays versus the Texans, but guaranteeing Mack s effectiveness is no longer as automatic as it once was. The Bears 2020 season will forever be remembered for the team s substandard offense, but Mack hasn t played like the former NFL player of the year he s paid to be.
