Paul Sass defeated Jacob Volkmann via submission (triangle armbar) at 1:54 of the first round

Well, this is an unexpected story. UFC ring girl Arianny Celeste was arrested for domestic violence this morning at 7:30 AM according to TMZ. A search of the "in-custody inmates" at the clark county detention center shows that Arianny (Lopez in this case) is held on $3,000 bail with a hearing set for the 30th at 10:45 a.m.

There is no word on the victim of the battery, so speculation would be inappropriate.

One can only assume that she will not be working tonight's UFC 146 event, with duties likely falling to Brittney Palmer.

This is the latest in a very weird week for the UFC, which saw top star Jon Jones arrested for a DWI despite claims from him in the past that it was the last thing he'd ever do, and then word coming out that Jon had had his car towed previously for driving recklessly while on a suspended license after he was pulled over in a strip club parking lot.

We'll have more on the situation as details emerge.

Update: Yahoo! Sports' Maggie Hendricks got a quote from UFC president Dana White:

"Arianny is our baby. She has been with us for over five years. She is a good girl and an amazing ambassador for the UFC. I don't know all the details of what happened but we have her back and support her 100 percent," White told Yahoo! Sports.

Glover Teixeira defeated Kyle Kingsbury via submission (arm-triangle choke) at 1:53 of the first round

Glover Teixeira made a huge splash in his UFC debut, completely dominating Kyle Kingsbury on his way to a submission victory at just 1:53 of the first round in their preliminary UFC 146 bout. He started rocking Kingsbu on the feel pretty much immediately and finally dropped him with an uppercut about a minute in. He showed that his ground game was as fearsome as his standup but methodically working into mount an eventually setting up an arm-triangle choke for the victory. After a very long wait to make his his way into the octagon, Teixeira definitely made the most of it.

Teixeira opened with some solid shots on the feet, mostly dangerous right hooks. Kingsbury tried to respond with his own right hands, but ate an uppercut that hurt him. Glover jumped him on the ground, sunk in his hooks, and immediately transitioned to mount. Teixeira rained down elbows while Kingsbury tried to roll unsuccessfully. Teixeira latched on an arm triangle and jumped out to the side, and Kingsbury could do nothing else but tap.

Teixeira had long been considered one of the top light heavyweights outside of the UFC, but couldn't fight due to visa issues. He extended his winning streak to 16, while Kingsbury dropped his second bout in a row.
