Khalil Mack leaves Chargers game with elbow injury as ‘ugly’ replay raises bigger concerns

Los Angeles Chargers linebacker Khalil Mack left Monday night’s game against the Las Vegas Raiders with a left elbow injury after an awkward collision. The 34-year-old was ruled out before halftime with his arm in a sling. With Joey Bosa already gone, Mack’s absence leaves the Chargers thin on pass rush depth heading into Week 3.
