Matt Forte, the do-everything running back who spent most of his career as the Bears’ best running back since Walter Payton, is retiring.

“To the McCaskey family and the entire Chicago Bears organization, thank you for the honor of allowing me to be a part of the rich Chicago Bears tradition and to run in the footsteps of greats like Gale Sayers and Walter Payton,” Forte wrote on Twitter. “Lastly, to all Chicago Bears fans, you’re truly the best fans in all of professional sports. Thank you for embracing my family and me from day one! The roar of the crowd at Soldier Field as I’d break a run or make a big catch will forever be ingrained in my mind.
