IN BRIEF : Fallen Boxer in Critical Condition

A boxer who suffered a stroke and collapsed during a fight at the Canadian-American Days Boxing Championships in Myrtle Beach remained in critical condition today, a hospital spokeswoman said.

Guydell Williams, 18, of Jackson, Tenn., was in the surgical trauma intensive care unit at the Medical University of South Carolina in Charleston, where he has been since Wednesday night, a spokeswoman said. Williams’ stroke was traced to a lack of blood flow to the brain due to an abnormality in a major artery, neurosurgeon Brian Cuddy said. The abnormality could have resulted from a blood clot or a blow in the fight, Rick Gaskin, administrative director of the Horry County Youth Club that put on the boxing match, said Cuddy and other doctors told him.

The boxer collapsed Wednesday night at the Myrtle Beach Convention Center after losing the last fight of an 11-bout event. Williams also had lost an earlier bout that day.
