Defensive end Mario Edwards Jr. plans to leave school early, a source told ESPN's Joe Schad.
Junior cornerback P.J. Williams, meanwhile, wrote on his Twitter page Tuesday that he will enter the 2015 draft.
I will be taking my talent to the NFL, I wanna thank the NoleNation for some of the best 3 years of my life, the memories will never fade!!💯— Pj Williams (@PjWilliams_26) January 6, 2015
Edwards is rated No. 46 overall, according to ESPN's Scouts, Inc. The 6-foot-3, 294-pounder is a powerful edge rusher who can shed blocks and deliver big hits. He had 44 tackles -- 11 for loss -- and three sacks this season.
ESPN NFL Draft Insider Mel Kiper Jr. has listed Williams as the sixth-ranked cornerback. ESPN Insider ranks Williams 61st overall and No. 7 among cornerbacks, with a grade of 77.
Williams started 24 of the last 25 games for Florida State and was the defensive MVP of last season's BCS National Championship. He was fifth on Florida State in tackles (74) and third in tackles for loss (6.5) this season, and his 11 passes defensed ranked 12th in the ACC.
Ronald Darby, Florida State's other talented junior cornerback, has not announced whether he intends to join Williams in the NFL draft. Eddie Goldman also could skip his senior season and declare for the draft.
FSU also lost linebacker E.J. Levenberry, as he will be transferring. Evenberry had 39 tackles as a freshman last season, but played sparingly as a sophomore this season.
