Well, it was a bit of a weird one cus Texiera wasn't really 'putting it on him' when he had him down on the ground. It was a sustained beating yeah, but not many of the shots were particularly impactful, and when an impactful one was landed, Texiera reverted back to controlling him with his grappling.

That said, bit concerning if, like you said, Smith handed the referee his teeth mid-pounding. I think everyone's to blame for this fight. Smith's corner (for not throwing in the towel), Smith (for gassing himself out), Texiera (for not just unloading on Smith to force a stoppage) and the referee (for not recognising Smith was done). A cavalcade of shitty decisions lead to this weird outcome.

How about Reem though? Came back from the brink of death to absoultely destroy a man who just lost his daughter. Ruthless.
