Butkus was not only one of the most revered and respected legends of the NFL, he also had a career in entertainment and remained a popular figure around the Bears franchise, even drawing laughs for his hilariously unfiltered social media posts.

Tributes poured in on social media after the news of Butkus' death. The Washington Commanders, who hosted the Bears on Thursday Night Football, also tweeted their condolences and held a moment of silence in his honor before the game kicked off. The Packers, the Bears' longtime rival who Butkus still loved to troll on social media even though his nephew works for Green Bay as an assistant coach, also sent their condolences.

The final NFL game Butkus attended was the Week 1 Packers win over the Bears at Soldier field, where it was a family affair.

Others from around the NFL and in Chicago sent in their condolences as well, as did the University of Illinois, where he was also a legend on the Fighting Illini.
