Tackled Cowboys Cheerleader Video?

During the Cowboys's Thanksgiving Day game against the Miami Dolphins, cheerleader Melissa Kellerman was tackled at the end of a play. Where can I see the video?
Was the Cowboys cheerleader tackled on purpose or was it an accident? I watched the play on TV but I couldn't clearly see what happened so I decided to see the youtube video.
Was the Cowboys cheerleader hurt after she was tacked? Is she alright now?
I noticed that the players barely apologized to her after the incident. Please post the youtube video if you can find it.

The Cowboys tight end took down a Cowboys cheerleader who was in his path on the sideline after he made a catch.
The Cowboys cheerleader was OK after the tackle, she even tweeted that the guy wasn't even strong enough for her and that got her in a lot of trouble.
The Cowboys forced the cheerleader to close her Twitter account because of her comments even though she didn't say anything inappropriate.
Here's the youtube video of the moment the cheerleader is tackled.
