The refs originally threw a flag for targeting, but picked it up after three of the refs came in and realized that the Parks hit was extremely legal.
"I thought the officials did a great job with that," Rich Rodriguez said after the game. "Three of them knew that he turned his shoulder and it wasn't targeting, and they got the call right, so I thought it was a good piece of officiating."
While he was on the ground for a pretty good chunk of time after the hit, Villamin did come back in the game in the second half.
And was also making jokes on Twitter after the game:

So at least we know that he's okay, and that Will Parks hit him cleanly and didn't leave any long-term health problems with him after it.
By the way, Marquis Flowers really enjoyed this hit. Probably more than a normal human being should:
