A toxicology report has revealed the cause of death for former Hawaii quarterback Colt Brennan.
TMZ Sports reports that the toxicology report shows Brennan died from an accidental drug overdose. Brennan had multiple substances in his system, including fentanyl, methamphetamine, amphetamine and ethanol.
Brennan died in May at the age of 37. He was in the fifth month of an inpatient program and said to be doing well before the overdose.

He completed 70.4 percent of his passes for 14,193 yards, 131 touchdowns and 42 interceptions. The 131 touchdown passes rank fourth all time in NCAA Division I FBS history.
