Fight video: Mercer takes out Sylvia in extremely short time

Things that take 12 seconds:

1. The entire Olympic field runs the 100-yd dash and has their post-run celebration.

2. The Chicago Blackhawks broke their playoff losing streak after a 12-second overtime.

3. Ray Mercer knocked out the 310-lb former UFC champion, Tim Sylvia, at the Adrenaline 3 card in Alabama this weekend. Sylvia, who has wins over Andrei Arlovski, Jeff Monson and Ricco Rodriguez, was said not to be taking this fight seriously. His own teammate, Jens Pulver, said that Sylvia was making a mistake in taking on the fight. A 12-second knockout seems to prove Pulver right.
