UFC middleweight Luke Rockhold receives backlash after he posts pic of himself grabbing a tiger's testicles

UFC middleweight contender Luke Rockhold is in Thailand along with his American Kickboxing Academy teammate Mike Swick. Rockhold stopped over at a local tiger zoo, where he proceeded to post this ... rather disturbing picture of him grabbing a tiger's by the balls. The caption of the photo reads "Who's your Daddy".

The general response on Rockhold's Instagram was anything but kind. A sampling of the comments include:

"Massive fan but now just think ur a dick! Hope bisping fucks u up! Idiot mam"

"idiot. Hope bisping beats your ass"

"You got some issues man. Not cool and just weird."

"Hate to be your pets when cameras aren't rolling....sick fuck....."

After receiving heavy backlash even from his fans, Rockhold posted this message apologizing to anyone who was offended, as well as posting the full video to provide context:

"For those of u who think it was disrespectful I'm sorry. Was so minor just joking around. I was way too scared and would never do anything harmful to any animal."

Rockhold currently does not have a fight booked, but he's likely to face one of Lyoto Machida or Michael Bisping, the latter having just TKO'd Cung Le in Macau last weekend.
