A Sullivan South football player died during the first game of the season in Knoxville.
The Knox County Medical Examiner says Jake Logue died from natural causes.. due to a faulty heart valve.
Logue had a bicuspid aortic valve.. which is a defect that results in two leaflets or cusps instead of the normal three. Logue.. a linebacker and co-captain.. collapsed in the third quarter of Sullivan South's game at Knox West in August.
