Return animation to original position?

 if (something happens){
     animation.returntoOriginalState;
 }

I want it to be like the animation never happened.

I have a guy that hits slowly with a club. If the player isn't in the area, I would like the club to return to it's original position so that it's as if the animation never happened and the animation can be called again.

Also, on a semi-related note, the club has a trigger collider around it, if it was at all possible to make it so that the collider still triggers on it's animation route, that would be awesome too!

Thanks!
