McKie, an undrafted free agent out of Temple, spent time with the Philadelphia Eagles and Dallas Cowboys before joining the Bears in 2003. He began his Bears career as a member of the practice squad before being elevated to the active roster on Nov. 21, 2003
"I just want to thank the Bears organization and the fans here in Chicago, it's been a great run," McKie told ESPNChicago.com. "I pretty much knew when Mike Martz was named offensive coordinator that there wasn't going to be a high priority placed on the fullback position.
"But I'm glad the Bears did this now, as opposed to after mini-camp or during training camp."
Most think the move was because McKie doesn't fit the Mike Martz system. I think it was to show fans that they are really done with the fullback dive.
