Fresh off three touchdowns and a Tostitos Fiesta Bowl win, Oklahoma State receiver Justin Blackmon announced he will enter the NFL draft and forego his remaining year of eligibility.

Blackmon made the proclamation to ESPN's Heather Cox in a postgame interview after catching eight passes for 186 yards in the Cowboys' 41-38 overtime victory over Stanford.

Blackmon's announcement had become a foregone conclusion in recent weeks. The two-time Fred Biletnikoff Award winner told ESPN.com on Dec. 7 that he was "pretty sure" the Fiesta Bowl would be his last collegiate game.

The junior wideout even participated in Oklahoma State's senior day festivities.

Entering Monday night's game, Blackmon had 113 receptions for 1,337 yards and 15 touchdowns this season, ranking No. 2 in the nation in receptions per game and No. 8 in receiving yards per game.

Scouts Inc., has the 6-foot-1, 211-pound Blackmon rated as the No. 10 prospect in April's draft.
