The official weigh-in event for UFC 106: "Ortiz vs. Griffin 2" is set to take place at the Mandalay Bay Events Center in Las Vegas, Nevada, on Friday, November 20, 2009.

It is currently scheduled to air LIVE right here on MMAmania.com, as well as on several other online destinations, via streaming video. The first fighter is expected to tip the scale at 7 p.m. ET.

As usual, MMAmania.com will provide the latest coverage of the UFC 106 weigh-ins, as well as provide a detailed recap of the festivities as soon as they conclude.

UFC 106 features a rematch between former light heavyweight champions, Tito Ortiz and Forrest Griffin, filling the gaping main event void left by Brock Lesnar, who was forced to withdraw from his heavyweight title defense against Shane Carwin because of a serious illness.

Top welterweight contender, Josh Koscheck, will once again step up on relatively short notice to see if the hard-hitting Anthony Johnson belongs among the division’s elite.
