Selection Sunday is upon us, which means March Madness has officially arrived. The biggest hoops holiday of the year -- the day the selection committee unveils the field of 68 teams in the NCAA Tournament -- is now just hours away.

Who will be left out? Who will fall on the right side of the bubble? Which teams will snag No. 1 seeds? There are plenty of questions that have been asked for weeks that will soon be answered.

On Sunday evening at 6 p.m. ET, TBS will air the bracket reveal live. Let the countdown -- and the drama -- begin.

Make sure to tune in to CBS Sports HQ from 6-9 p.m. ET on your computer or mobile device to catch the March Madness bracket reveal and instant tournament breakdown which will feature interviews with coaches in the Big Dance.   

Here's how and when you can catch the Selection Sunday reveal this year:
