PITTSBURGH (AP) — The Pittsburgh Steelers are running up wins, and running out of healthy inside linebackers. A week after Cole Holcomb’s season ended with a knee injury, veteran Kwon Alexander is going to join Holcomb on injured reserve after sustaining a “serious” left leg injury in the first quarter of a 23-19 win over Green Bay. Steelers coach Mike Tomlin said Alexander was being evaluated but the prognosis was “not promising.”
