Coach Marc Trestman and some members of his staff at Wednesday’s practice wore gray T-shirts with pink Bears logos on the front and the slogan “Real Bears Fans Wear Pink.”

The attire is part of the NFL’s annual breast cancer initiative which begins this week with what the league has dubbed Breast Cancer Awareness games including the Bears’ matchup against the Saints at noon Sunday at Soldier field.

Prior to kickoff breast cancer survivors will help hold the 4th Phase Flag on the field. The Bears and 4th Phase flags used after the Bears score will be branded in all pink. And Buckingham Fountain in Grant Park will be turned pink in the days leading up to the game with help from the Chicago Park District in conjunction with the Lynn Sage Cancer Research Foundation.

The Bears and their charitable beneficiary Bears Care will once again sell “Real Bears Fans Wear Pink” T-shirts to benefit area organizations that provide care and support to breast cancer patients and their families as well as offer access to breast health services to low-income women.
