Andrew Luck is preparing to play in a regular season game for the first time since the end of the 2016 season.

As Luck spent all of last year rehabbing from shoulder surgery, he feared he might never be able to play football again.

"I was scared, scared in my core, in my insides. There was a time I was very scared about football, and about my place in football," the quarterback said.

Luck admitted the toll the injury took on his mental well-being.

"I was a sad, miserable human," he said. "I was not nice to myself, nor was I nice to anyone else. I was a miserable SOB to be around. I was nervous. I was scared."
