The Stampeders' sophomore lineman was honoured during the CFL awards banquet Thursday from the Queen Elizabeth Theatre.
Jones received the award in voting by the Football Reporters of Canada and nine CFL head coaches.
Jones was the CFL's top rookie last year.
The six-foot-two, 318-pound Jones, a 23-year-old native of Weyburn, Sask., played all 18 regular-season games for the Stampeders and anchored an offensive line that allowed a league-low 26 sacks.
Calgary also led the CFL in rushing, averaging 144 yards per game.
Jeff Perrett of the Montreal Alouettes was the finalist.
