The degree completes seven years of study.
Duvernay-Tardif, 27, posted a photo of himself on Twitter on Tuesday following the commencement wearing a lab coat with "Dr. Duvernay-Tardif" across the back and his No. 76 in Kansas City's red-and-gold colours.
The Chiefs picked Duvernay-Tardif in the sixth round of the 2014 draft, but despite playing at a smaller Canadian school, he quickly earned a starting job. It's an honour to be a member of that community and I take the responsibility seriously.
It's been a meteoric rise for Duvernay-Tardif, a converted defensive lineman who cracked the Chiefs' 53-man roster as a rookie before becoming a starter in 2015.
For now, his goals are the same as any other football player - he wants to win the Super Bowl.

"With the NFL's rules regarding dress code being so strict I'm not sure how well it's going to go", he said.
"Medicine is an opportunity to do something you really love and you're passionate about for up to 40 years", he said. I've been able to follow a passion while playing another - THANK YOU!
As he told ESPN, Duvernay-Tardif plans to do his residency in emergency medicine. He said being a part-time resident might be hard, but he's managed to find away in the past.
Pro football players are often stereotyped as being unintelligent, but given that the 32 NFL rosters all include 53 players, not to mention those on injured reserve, the league is actually rather eclectic when it comes to education. "He was trusting me that I was going to be accountable and I was training here (in Montreal)".
Reid's mother, Elizabeth, also graduated from McGill's medical school.
Duvernay-Tardif said he wouldn't have time to celebrate his graduation.
