The price is for $2 1 million and also includes $10 million fully guaranteed, a source told ESPN’s Adam Schefter.
Callahan’s 2018 season ended in December, when he broke his left foot at the Bears’ 15-6 victory on the la Rams at a Sunday night game.
Callahan, 27, emerged within the past 3 years as a very important member of the Bears’ secondary.
An undrafted free agent outside of Rice at 2015, Callahan also picked off two passes from the 2017 season.
He received the 11th-best grade (81.4) among cornerbacks from Guru Football Focus last season.
