Dallas Cowboys cheerleader Melissa Kellerman became an Internet celebrity overnight, when the video of her being tackled by Cowboys tight end Jason Witten during their game against the Miami Dolphins went viral.

After catching the ball from quarterback Tony Romo, Witten simply ran out of bounds and wound up taking his cheerleader down. The incident seemed to stun Kellerman, 22, rather than actually injure her, who dusted herself off and got back on her feet, smiling and a little embarrassed. Kellerman has been a Cowboys cheerleader for four years now.

Meanwhile, after posting a couple of tweets about the incident, Kellerman's Twitter account has, rather mysteriously, disappeared.

Not hurtin' today, like some of y'all thought I would be! Our TE isn't as tough as he looks...That or I'm WAY tougher than I look. :) tweeted Kellerman, who later also said: I'm not the best at Jason Witten trust falls. ;)
