DES MOINES, Iowa -- Authorities say a 16-year-old boy has died at an Iowa hospital less than five days after collapsing during basketball practice.

Woodward-Grainger junior Drew Jacobson was flown to Mercy Medical Center in Des Moines last Wednesday evening. Hospital spokesman Gregg Lagan said Tuesday the boy died at 7:15 a.m. Monday. Lagan directed questions about the cause of death to the Polk County medical examiner, who didn't immediately return a call from The Associated Press. Lagan says the boy had to be revived twice with a defibrillator before being flown to the hospital.

School district Superintendent Brad Anderson told The Des Moines Register that Jacobson's collapse wasn't the result of contact or a specific play at practice and that coaches kept Jacobson stable until medics arrived.
