As previously reported, the Undertaker losing to Brock Lesnar went as planned last night. Back in 2010, Undertaker wanted to work a WrestleMania program with Lesnar and reportedly was willing to lose and end the streak then.
Despite rumblings of the long rumored Undertaker vs. Sting match taking place at next year's WrestleMania, the feeling backstage is that after last night's match, the Undertaker is done and officially retired. We should know more on RAW tonight.
