In a corresponding move, Toronto recalled infielder Richard Urena from triple-A Buffalo.
Diaz was forced to leave Toronto’s 2-1 victory over the Tampa Bay Rays Sunday in the top of the fifth inning after stepping awkwardly on first base and falling to the ground a few steps later. He was unable to place any weight on his left leg and was seen in a walking boot with crutches after the game.
In 110 plate apperances with the Blue Jays this season, the 27-year-old is batting .216/.273/.431 with six home runs and 13 RBI.
Urena, 22, made 75 plate appearances for Toronto last season, hitting .206/.270/.309.
In an earlier move, the Blue Jays recalled right-hander Jake Petricka from triple-A to replace closer Roberto Osuna, who was charged with assault Tuesday by Toronto police.
