Welcome to the UFC 123 live blog!

I, featured columnist Derek Bolender, will be your host for this evening's festivities. I am currently seated cageside inside the Palace of Auburn Hills in Auburn Hills, Michigan. We are about 30 minutes north of Detroit.

Please follow along for a round-by-round analysis of tonight's fights as they transpire. I will also give my observations of what is going on inside the arena and on press row and attempt to set the scene.

The undercard will start at or near 7:20 pm (et) with the main pay-per-view card scheduled to go live at 10:00 pm (et).

Follow me on Twitter (@DerekBolender) for all post fight news and notes.
