Former New Orleans Saints player Scott Ross was found dead Sunday inside a vehicle at an East Broussard Road church in Lafayette on Sunday morning, officials said.

Ross, 45, was a Saint in the 1991 season after playing college football at the University of Southern California.

Lafayette Parish Sheriff’s Office deputies reported no signs of foul play, and the parish Coroner’s Office has ruled Ross died of natural causes.

Ross was among a group of former NFL players who sued the National Football League after suffering from head trauma.

The lawsuit said Ross had severe memory loss, cognitive decline, dementia and chronic traumatic encephalopathy, a condition caused by repetitive sub-concussive and concussive blows to the head.
