One Of The Nastiest Swellings I've Ever Seen

[Wayne]

Actually I think Rahman's conition was more serious. In that fight he received a hematoma, which is a bleed within the cranium.

If it were intracranial he wouldn't be able to fight in the States anymore. Maybe it was above the cranium?

man that Rahman shot? What causes that? is there any lasting effects?

Nah, that was caused by Evander's 'Third Punch'. At least Chris Byrd had the common sense to stay away from it.
