After receiving a concussion and facial fracture in a match with Rey Mysterio, Undertaker was out of action from May 28 2010 to October 24, 2010. He had returned August 15, 2010 for SummerSlam, but had a scripted exit (attacked by Kane) before he could compete. He then lost to Kane again at Bragging Rights on October 24.
