Brown stepped down in December after 16 years with the Longhorns, winning the national title after the 2005 season.
Brown will appear on "College Football Countdown" and offer pregame, halftime and postgame commentary for the games on ABC, including "Saturday Night Football." He will work with host John Saunders and former Florida State quarterback Danny Kanell.
ESPN also said Thursday that former Miami and North Carolina coach Butch Davis will serve as an analyst for ESPN2's studio coverage on Saturdays.
