Who injured Brian Stann and forced him to withdraw from UFC on FOX 4?

If you're training for a middleweight main event on the FOX network, it's probably not a good idea to roll with a guy nicknamed "The Savage."

But that didn't stop Brian Stann from tangling with Ultimate Fighting Championship (UFC) Heavyweight Shawn Jordan in preparation for his "All American" showdown against Hector Lombard on Aug. 4 in Los Angeles.

Lesson learned.

Jordan "went for a hip throw" and inadvertently landed on Stann's shoulder, causing a "grade two separation of his right AC joint." The injury, which won't require surgery, was severe enough to keep him out of the cage until later this year.

After the jump, Stann breaks it all down for the gang at FUEL TV (via MMA Weekly):

"Shawn Jordan and I were in the cage and he went for a hip throw and he landed on my shoulder, all 275 pounds of him. I think he slipped. He knows not to land on me. But it happened. And you know you could hear the crack right away. It’s one of those feelings were you know when you are hurt and when you are injured. It’s a grade-two separation of my right AC joint, which is what I am feeling right now. It’ll be six to eight weeks recovery, but no surgery, thankfully. Hopefully, I can heal this up real quick and get my full range of motion back. But, right now I can’t even pick my hand up. You know, probably the biggest issue I am going to face now is trying to return too early.I would like to get back in the gym and try to hit some pads in 4-5 weeks, but the doctors were very adamant that even at six weeks I am not going to be able to put the pressure on the shoulder to wrestle the way I should. I am trying to stay in shape using my other three limbs in the meantime."

Following Stann's injury, Lombard was packed up and shipped off to the UFC 149 pay-per-view (PPV) fight card in Calgary to face Tim Boetsch. "The Barbarian" became available when his original opponent, Michael Bisping, blew out his knee in training.

There's a lot of that going around these days.

Mauricio Rua and Brandon Vera have taken over as UFC on FOX 4 headliners at the Staples Center -- assuming they can stay healthy for the next two months.
