Just playing ball last season was rough, as Walker dealt with multiple injuries. The 6-foot-5, 292-pounder injured his left wrist in Week 4’s road win over the San Francisco 49ers. Following surgery, he returned to practice within days, outfitted with a short, fingerless black cast that reporters quickly took to calling a club. But swelling under the cast sidelined Walker again, and he didn’t return for Week 5 and was limited for weeks afterward.
