This is a tough one.

Tough indeed. Prayers coming your way Big Steve. You are one of a kind. Have always appreciated our talks on life and football. Difficult story to tell Dan, but you delivered. Bears fans stirred by this today. #TeamMongo. https://t.co/bnuu2NIUYs

Saddened to learn of the ALS diagnosis for Steve McMichael. I covered most of Mongo's Bears career for the Chicago Tribune. In addition to being a defensive tackle, McMichael did some kicking while at Texas. Thus, he was happy to join our Fred Mitchell Award selection committee. pic.twitter.com/GZQkULYf6z
