Justified alum Mykelti Williamson will guest-star on CBS' upcoming freshman drama Scorpion, TVGuide.com has learned exclusively.

Scorpion stars Elyes Gabel as eccentric genius Walter O'Brien, who builds a team of other super-geniuses to help solve the world's most complex problems. Williamson will appear in an October episode as Gen. Ned Walker, a hard-edged, lifelong soldier in command of the military-controlled Montero Nuclear Reactor, which comes under threat. Initially wary of the presence of a rag-tag bunch of outsiders on his military base, Gen. Walker is at odds with Walter & Co. — until he sees them in action, of course.
