Rondale Moore, an NFL wide receiver whose career was derailed by back-to-back season-ending knee injuries in training camp, has died at 25.

Moore was a standout player at Purdue University and had an encouraging start to his NFL career with the Arizona Cardinals.

Authorities said Moore was found Saturday in the garage of a home in his hometown of New Albany. 

Police Chief Todd Bailey said investigators believe he died from a self-inflicted gunshot wound. The death remains under investigation.
