Passage:In late 2010, Mathews often worked as the color commentator on Raw due to Jerry Lawler's increased in-ring competition. On April 3, 2011, Mathews commentated the majority of WrestleMania XXVII, though he received a 'Stone Cold Stunner' from an angered Stone Cold Steve Austin, cutting his night short.

He then became the alternate spokesman for the Anonymous Raw General Manager, when Michael Cole was not commentating. He then using the new catchphrase "The Anonymous Raw General Manager says...", before reading each e-mail. On the April 25 episode of Raw, Mathews announced that the Jim Ross and Jerry Lawler vs. Michael Cole and Jack Swagger match at Extreme Rules will be a Country Whipping match, which Cole and Swagger won. At the following pay-per-view, Over the Limit, Mathews supported Lawler, Bret Hart and Eve Torres in having Michael Cole kiss Lawler's foot. The following night, again as the spokesman for the anonymous Raw General Manager, Mathews read the e-mail that denied The Miz's request for another title shot, seemingly done with John Cena.
