LSU star cornerback Greedy Williams declared Sunday afternoon that he will forego the rest of his college eligibility and and enter the 2019 NFL Draft.

Williams will not play in the Fiesta Bowl, an LSU official confirmed.

Several media organizations predict Williams will be a Top 10 pick in the NFL Draft, including CBS Sports, which predicts Williams will be selected No. 8 overall.

Williams, a 6-foot-3, 184-pound redshirt sophomore was named to the freshman All-SEC team last season, and this season he has been named a semifinalist for the Thorpe Award, given to the nation's top defensive back.

Williams made the announcement on Twitter, thanking former LSU coach Les Miles for recruiting him, current coach Ed Orgeron for believing in him and the players who make up his "LSU Tiger Family."

Williams' Twitter post occurred during Orgeron's introductory Fiesta Bowl teleconference, and Orgeron said he did not expect Williams to make the announcement yet.

"I wish him the best, obviously," Orgeron said. "If that's what he wants to do, we wish him and his family the best. I didn't know that was posted yet. We were going to have a meeting, a final meeting."

Orgeron said he will be speaking with all his draft-eligible players soon, a discussion that will decide what kind of roster the Tigers will have in the bowl game and entering next season.

Orgeron mentioned how former LSU running back Derrius Guice played in last season's Citrus Bowl loss against Notre Dame. Guice rushed for 98 yards on 21 carries, declared early for the NFL draft and was selected in the second round by the Washington Redskins.

"I talked to Derrius about representing the state of Louisiana," Orgeron said. "He’s done a great job about finishing strong. And, to me, this is about your team. This about not an individual. It’s one team, one heartbeat. So, hopefully we can get all our guys playing. I’ve talked to some guys. I haven’t talked to everyone yet. I probably will have a final decision from most of the guys this week.”

Williams has started in every game this season, anchoring a pass defense that ranks 32nd nationally with 196.2 passing yards allowed per game. LSU is tied at No. 10 in the nation with 16 total interceptions, and Williams has two interceptions this season.
