Senior, a Montreal native, played college football at Mississippi State, starting 38 games at right tackle from 2014-16. Senior was selected by the Seattle Seahawks with the 210th overall pick in the 2017 NFL Draft. He was also taken by the Edmonton Eskimos in the fifth round of the CFL Draft.
Counting starting right guard Laurent Duvernay-Tardif, the Chiefs now have two offensive linemen who hail from Montreal, Canada, on the roster. Add in Ryan Hunter, who is originally from Ontario, and that makes three offensive linemen on the Chiefs from north of the border.
