Duvernay-Tardif was the 200th player selected in the draft. Based on the contract signed by last year's 200th pick, Baltimore defensive lineman Kapron Lewis-Moore, Duvernay signed a four-year deal that would be worth about $2.25 million and includes a signing bonus of about $88,000.
The signing of Duvernay-Tardif deepens the reputation of Chiefs general manager John Dorsey for finding players in nontraditional places. The Chiefs learned of Duvernay-Tardif, who played in college at McGill in Canada, at this year's East-West Shrine all-star game. Duvernay-Tardif is also a medical student.
The Chiefs' other sixth-round pick, offensive lineman Zach Fulton of Tennessee, signed with the Chiefs on Tuesday.
