LSU's leading tackler, linebacker Kwon Alexander, announced via Twitter Wednesday that he's leaving the Tigers early to enter the 2015 NFL draft. He's the first of as many as seven underclassmen who might take the plunge.

Alexander, who had a team-leading 11 tackles in the Tigers' 31-28 loss to Notre Dame in Tuesday's Music City Bowl, thanked "team, coach and LSU nation" for their support and that he consulted with family over the decision. He closed the tweet with the hashtag #FOREVERLSU.

The 6-feet-2, 227-pound junior from Oxford, Ala., finished the season with 90 tackles, 7.5 for loss. He also had five quarterback hurries and two forced fumbles.
