The good news for Toronto is that Loperfido did not end up fracturing anything but after taking a pitch like that to the knee, he will surely be out for at least a short period of time.
After the game, teammate Jeff Hoffman posted a picture of Loperfido in good spirits eating a chicken parm in the clubhouse which is definitely a good sign that the injury is not too bad.
Hopefully Loperfido will not be out too long as he has been one of the Blue Jays best hitters lately as he currently has 3 homeruns and 10 RBIs in 24 games this season with a .389 batting average.
