It wasnt intentional, I actuall rewatched the game last night and made a note of following Gray's eyes during the foul, and as you can see in the picture, Gray's eyes dont leave the ball
for a second. It WAS very very careless on his part tho, and I noticed that Gray was getting really upset with Mickey during the game starting with when Mickey smacked him in the face :P  

You can see Jordy landing on his knee a little as he tumbled out of the after the foul, but there's no obvious limp from him for the rest of the game
