NORMAN, Oklahoma - Sixteen Oklahoma players participated in the Sooners' annual Pro Day inside the Everest Training Center Wednesday, giving them an opportunity to work out for gathered NFL scouts and general managers before the upcoming NFL Draft.

Nearly every NFL team was represented at the event, with just the Oakland Raiders missing in attendance. From the Sooners, 15 of 16 players participated in on-field activities, with Ryan Broyles still recuperating from a knee injury.

Oklahoma is No. 4 in the nation in players picked in the NFL Draft, with 350 former Sooners being selected in the draft, 42 of which were selected in the first round. Two seasons ago, with Sam Bradford, Gerald McCoy and Trent Williams being selected No. 1, No. 3 and No. 4 respectively, the Sooners became the first school with three players selected in the top 4 of the draft.

The NFL Draft will begin Thursday, April 26 with the first round starting at 7 p.m., ending Saturday, April 28, 2012.
