JOHNSON CITY — Austin Herink headed up another comeback for the ages for East Tennessee State’s football team. The senior quarterback engineered two late scoring drives and the No. 25-ranked Bucs rallied from a 15-point deficit with a little over five minutes left in regulation to edge Western Carolina 45-43 in a three-overtime thriller Saturday evening at Greene Stadium. ETSU won the new “Blue Ridge Border Battle” trophy for the rivalry and kept pace with Wofford atop the Southern Conference standings.
