Hummel (groin) has been ruled out ahead of Sunday's game against the Bengals.
Hummel suffered a groin injury during the third quarter of Sunday's 36-31 loss to the Bills. The linebacker is considered week-to-week as he deals with the issue, so the fact he's ruled out for Week 2 is no surprise. Jake Hansen will likely continue to fill in for Hummel for as long as he remains sidelined.
