The Bears last played in the Hall of Fame Game in 2005, defeating the Miami Dolphins 27-24.
Star linebackers from both clubs - Ray Lewis (Ravens) and Brian Urlacher (Bears) - were elected to the Pro Football Hall of Fame in their first year of eligibility last Saturday.
The preseason opener is the start to the 2018 Pro Football Hall of Fame Enshrinement Week that will feature the enshrinement of Ravens' great Ray Lewis into the hall two days later.
The contest will take place at Tom Benson Hall of Fame Stadium in Canton, Ohio, and is scheduled for August 2 at 8 p.m. ET.
The Bears are kicking things off a little early this year. That will give Ravens coach John Harbaugh and his staff an extra week to evaluate young players, but it also will lead to more injury concerns because of the increased summer practice time and an extra preseason game. The two teams will now play five preseason games.
Lewis, the second Ravens player ever drafted, will join the first-ever drafted, tackle Jonathan Ogden, as Hall of Fame inductees. Both were selected by Baltimore in the first round of the 1996 draft. They have gone 4-0 in the games, also topping the Cowboys in 1968, Jets in 1977 and Browns in 1990.
The rest of this year's class includes longtime general manager Bobby Beathard, linebacker Robert Brazile, safety Brian Dawkins, guard Jerry Kramer, receiver Randy Moss and wideout Terrell Owens.
