At around 24:32, JBL smacks the living shit out of Eddie with a steel chair, causing him to profusely bleed. This one's a fair bit disturbing compared to the ones I showed for Cena and Jericho, so be warned, as it is a little uncomfortable to watch.
At around 26:05, commentary states that Guerrero very likely has a concussion, but he still has the will to fight on (albeit fairly sluggishly).
In the end, it was Eddie who came out on top, whooping JBL's ass after the match as well, after he got himself purposely disqualified.
