Pittsburgh Steelers outside linebacker Alex Highsmith was injured just as he nearly recorded a drive-ending sack on Los Angeles Chargers quarterback Justin Herbert with a little over one minute remaining.  Herbert scrambled away and threw for a first down, but when the dust settled, Highsmith was headed for the medical tent.

This isn't the kind of body language you would expect out of a player attempting to rejoin the game, and we now know the reason why: Highsmith was deemed doubtful to return.

Injuries are utterly devastating the Pittsburgh Steelers three weeks into the regular season.  Alex Highsmith is a pivotal piece in the dynamic edge rushing duo with T.J. Watt, and now it will be up to second-year player Nick Herbig to shoulder the privilege of sacking the quarterback.
