Sword kill

This one is more difficult. A guy with a sword hits another guy with fast punches who somehow become paralyzed and very slowly begin to collapse. The other guy is placing his sword in front of the victim to fall on it.
thanks

Serenity ?
About 2:40 into the video is the beginning of the scene I am thinking of, the end is at 3:26, the video is made up of clips from the movie so everything is out of order.
