Ryan Kerrigan Purdue Boilermakers authentic Nike size MEDIUM jersey with stitched-on double layer cloth tackle twill name and numbers, the same style he wore as Big Ten Defensive Player of the Year and first-team All-American. The armpit to armpit measurement is about 23 inches. As shown on ESPN Outside the Lines, the vast majority of football jerseys sold on the internet are cheap counterfeits made in Asia with vinyl numbers made to look like cloth. This is a REAL Nike jersey stitched in the United States. BRAND NEW, NEVER WORN (NO PAPER TAGS). (Model: Mariah Coogan) ONLY ONE LEFT.
