NASCAR champion Tony Stewart said Sunday, "there aren't words" to describe his sadness after a crash that killed another driver Saturday night.

"People that witnessed it were horrified, they were extremely shocked by what they saw."

That tragedy on the track happened during a dirt track event in upstate New York.

Video just before that deadly collision shows Stewart and Kevin Ward, Jr., getting tangled mid-race. It caused Ward to spin out. Seconds after his car came to a stop, Ward got out and walked onto the track to confront Stewart after the wreck. That's when Stewart's car hit Ward, who later died at the hospital.

Sunday night, investigators said they were looking into the wreck but didn't have any evidence of criminal intent. Still, as police piece together what happened, the three-time NASCAR champion did decide to sit out Sunday's Sprint Cup at Watkins Glenn.

"I've decided not to participate in today's race at Watkins Glen," Stewart said in a statement. "My thoughts and prayers are with his family, friends and everyone affected by this tragedy."

"We talked last night and realizing, going through the night, gave Tony some time to sleep on it and I met with him this morning, and he feels strongly that this is the right thing to do," added Greg Zipadelli, competition director at Stewart-Haas Racing. "We at SHR support it and agree with it. Like I said, it's a difficult time for both parties."

Regan Smith replaced Stewart in his car.
