Daniel Te'o-Nesheim, who started 26 games for the Bucs at defensive end in 2012-13, died Monday at age 30, Hawaii TV station KITV reported.
No details were immediately available about his death. After four years in the NFL, Te'o-Nesheim was coaching at Hawaii Preparatory Academy in Waimea.
Te'o-Nesheim, born in American Samoa, was a third-round pick of the Eagles in 2010, but found his best NFL success with the Bucs. He had four sacks and 40 tackles in 2012, starting 14 games for Tampa Bay, and started another 12 games in 2013. Before playing in the NFL, he left the University of Washington as the school's career sacks leader with 30.
