A true freshman, Lubischer was redshirting this season after coming to Duke as part of head coach Ted Roof's second full recruiting class.
During his senior season at Boca Raton (Fla.) High, Lubischer played as a tight end, offensive lineman, and defensive lineman. He logged more than 80 tackles along with five sacks over his final two prep seasons - good enough to be rated as a two star prospect by Scout.com
Lubischer chose Duke over offers from Colorado State and North Carolina State.
With the departure of Lubischer, the Blue Devils will rely on a pair of true freshmen that are also redshirting. Ohio native Brett Huffman, who was rated as the nation's No.48 tight end and a three star prospect and William Ball, who was considered the nation's No. 68 TE and an two star prospect.
Duke has also received a commitment from Maryland's Danny Parker, who is rated a three star prospect and the No. 42 TE in the nation in the class of 2007.
