Doctors treating 8-year-old Jessie Arbogast, who was nearly killed in a shark attack July 6, say the boy may not have suffered brain damage despite a severe loss of blood.
Jessie's arm was reattached after being bitten off by a 200-pound shark.
"We're proceeding with . . . cautious optimism. Every day we seem to progress a little bit further," the boy's chief surgeon, Dr. Ian Rogers, said Sunday on NBC's "Today" show.
The boy remained in critical condition Sunday at Sacred Heart Children's Hospital.
Also, a shark bit a surfer Sunday a few miles from the Gulf Islands National Seashore area where Jesse was attacked.
The 48-year-old man, whose name was not released, suffered puncture wounds when the shark bit him on the leg.
He said he had noticed small fish and a large shadow below him before the attack, but hadn't thought anything was wrong.
