Sunday's AFC championship game between the Baltimore Ravens and the New England Patriots on CBS will serve as a sort of dress rehearsal for the network's coverage of the Super Bowl on Feb. 3, producer Lance Barrow suggested during a teleconference with reporters on Tuesday. We will have in this broadcast Sunday our whole setup that we will have down in New Orleans for Super Bowl XLVII, with all the cameras, with all the tape machines, with extra microphones on the field. ... With those extra cameras we're able to cover anything that happens on the field. Jim Nantz will provide play-by-play descriptions, while Phil Simms will handle color. CBS will also field two sideline reporters, Steve Tasker and Solomon Wilcots, something that it has not done during the regular season. They're kind of an added bonus, Barrow said. And, obviously, if we have a major injury, we will try to have them there to try to find out more information than maybe what we're getting from both P.R. staffs.
