Chicago Bears star Khalil Mack is dealing with a back injury (once again) and he hasn't practiced all week in advance of the Bears' Week 13 matchup against the Detroit Lions.

However, as has been the case all season, Mack is expected to play versus the Lions despite not participating in practice, per Adam Hoge of NBC Sports Chicago.

The Bears have been doing this with Khalil Mack all season. Since he's their best player on defense, Mack rests his back during the week so he can be effective during the games on Sunday.

Mack has 6.5 sacks on the season and 22 solo tackles. He's doing all he can to keep the Bears afloat in the NFC Wild Card race. Chicago, after starting the season at 5-1, has lost five straight games and is now 5-6 on the campaign.

The Bears, though, are 5-0 against the Lions since Matt Nagy became the head coach in 2018. Mitchell Trubisky, who will be starting at quarterback again instead of Nick Foles, is 4-2 in his career versus the Lions, so maybe the Bears can win in Week 13 to get to 6-6 on the season.

Nagy and Chicago general manager Ryan Pace are under immense pressure from the media and fans right now in the Windy City. Pace was the guy who drafted Trubisky over Patrick Mahomes and Deshaun Watson, while Nagy has regressed as the head coach since the Bears won the NFC North back in 2018.

If Chicago misses the playoffs this season, don't be surprised if both Nagy and Pace get fired.
