Oscar Diaz, a San Antonio welterweight, collapsed after the tenth round of his main event fight on Wednesday Night Fights, and was immediately taken to a local hospital for evaluation.

Rumors are floating around that Diaz is in "critical condition" and that it may be a brain bleed with the fighter "on a ventilator," but nothing concrete has been reported.

The scene in San Antonio was very scary, as the referee tried to get Diaz to respond to his questions. He was supported by his corner, and the referee said something like, "Nice trick. You're gonna get your fighter hurt here." Moments later, Diaz collapsed in the corner and the fight was stopped. Delvin Rodriguez was declared the winner via TKO, but that is now an afterthought.

Teddy Atlas at ringside expressed concern because of the fact that Diaz took a lot of punishment in an 11th round TKO loss to Golden Johnson in November of 2006, and had certainly taken several hard shots in this fight, which was pretty exciting and unfortunately and terribly marred by Diaz's injury.

We at Bad Left Hook sends our best wishes to Diaz and his family, and hope for a speedy recovery. Get well soon, Oscar.
