Check out Bob's weekly column in the Chicago Tribune this coming Sunday (but available online now) in which Bob breaks the news of former Chicago Bears wide receiver Muhsin Muhammad placing his 7,500-square-foot mansion in Libertyville, Ill. on the market for $1,128,000.

Also featured in the column: two previous items that have run here at Big Time Listings when they were rushed online as part of exclusives by Bob on the Chicago Tribune's Chicago Breaking Business blog:

--the news of publishing heiress and Johnson publishing CEO and chairwoman Linda Johnson Rice listing her 35th-floor condominium unit in the Carlyle building on Lake Shore Drive on Chicago's Gold Coast for $2,900,000 on April 5;

--former Chicago Bulls center Ben Wallace, now with the Detroit Pistons, selling his five-bedroom, 6,983-square-foot, traditional-style mansion on 1.74 acres in Lake Forest, Ill. for just over $2 million -- almost $1 million less than he paid for it in 2006.
