Scary moment last night as Oscar Diaz was fighting Delvin Rodriguez on ESPN2 last night. Diaz had taken a good number of shots throughout the fight and collapsed in his corner after the 10th round....

Welterweight Oscar Diaz, who collapsed in his corner after the 10th round of a TKO loss to Delvin Rodriguez on Wednesday night and was rushed to University Medical Center in San Antonio in critical condition, was being taken into surgery to relieve swelling on his brain early Thursday.

"He's got swelling and bleeding on the brain, he's unconscious and on a ventilator," Ron Katz of Rodriguez promoter Star Boxing told ESPN.com.

Katz said Donna Duva Brooks of Hall of Fame Promotions, Diaz's promoter, was at the hospital with Diaz. Katz said she told him that Diaz was being taken into surgery.

"It's not good. Obviously, he's in all of our prayers," Katz said.

I pulled the video because I thought ESPN2 did a great job in handling the scary moment and Joe Tessitore and Teddy Atlas explained everything that was going on as it happened. The video is scary when you consider everything that the fighter is going through now and if you choose not to watch I don't blame you....

It's amazing this doesn't happen more often, but great job by ESPN2 and hopefully everything turns it okay with Diaz.
