Hendrickson is slated to undergo core-muscle surgery later this week and is expected to face a six-week recovery, Adam Schefter of ESPN reports.
Ben Baby of ESPN.com previously reported that Hendrickson was on track to see a specialist for his injury and would be out this coming weekend against the Ravens. With surgery now on tap, Hendrickson could be sidelined for the rest of the regular season, and he's thus a candidate for injured reserve. The standout defensive end hasn't played since Week 8 and has notched 16 tackles, 4.0 sacks, one forced fumble and one pass defensed over seven appearances on the season.
