"He tried to feel me. That's weird, right?" Davis said afterward, according to Comcast SportsNet Bay Area.
The Star reported that Art Shell, the NFL's appeal officer, sent a letter to Smith confirming that video of the Davis incident, which was widely blogged about, was inconclusive.
"I fought the case, and I'm happy," Smith told the newspaper. "But (it doesn't erase) all the bashing of my name and all that stuff. I have kids, and my kids looked at it.
"I was just happy to get it resolved. It was hanging over my head since Week 3, and now it's not. People accuse you of stuff all the time. Stuff like this happens all the time. That's why you have the appeal process to go through, to get everything the right way."
