National Signing Day 2012 is finally upon us and the signed Letters of Intent are already beginning to roll in. National Signing Day is typically one of the most anticipated days of the year and 2012 will likely be no different.

The day has already had a few surprises, including Josh Harvey-Clemons heading to Georgia over Florida and Florida State, but the announcement that everyone is waiting for is wide receiver Dorial Green-Beckham. The 6-foot-6 wide receiver is ranked the No. 1 player in the country by Rivals.com and is believed to be deciding between Missouri and Arkansas.

Some of the other big names expected to announce their decisions on Wednesday include: No. 7 Eddie Goldman; No. 13 Tracy Howard; No. 18 Nelson Agholor; No. 19 Kyle Murphy, No. 27 Aziz Shittu; and No. 32 Andrus Peat.

The International Business Times will provide live updates throughout the day, but here is a list of a few of the biggest names expected to commit on National Signing Day.

UPDATE 1: Tracy Hamilton signs with Miami over Florida and Florida State. Hamilton says about signing with Miami, Why not win in my hometown and my city? Why not do it there?

UPDATE 2: Eddie Goldman goes with Florida State. A big, big pickup for the Seminoles. They've put together one of the best defensive lines in a long time with this recruiting class.

UPDATE 3: Dorial Green-Beckham, the No. 1 player in the country, decides on Missouri. 

UPDATE 4: Kwon Alexander spurns Alabama to sign with LSU. Alexander ripped off a pullover to reveal a LSU-inspired purple bowtie and suspenders.

UPDATE 5: The big surprise of the day is five-star wide receiver Deontay Greenberry spurning Notre Dame at the last second to sign with Houston. The 6-foot-3 wide receiver had been verbally committed to Notre Dame, but decided to make the switch after visiting Houston this past weekend.

UPDATE 6: The other big shock of the day came at noon when LSU commitment Torshiro Davis ditched the Tigers, who he committed to last year, in favor of Texas. The four-star prospect ensures that none of the top three players from the state of Louisiana will end up at LSU.
