GRAND FORKS, N.D. (AP) -- An amateur boxer in North Dakota who collapsed during a weekend fight has died.

The Grand Forks Herald reports that Grand Forks boxer Jerimiah "J.J.'' Moen died Wednesday morning at a hospital.

The 29-year-old Moen collapsed after the first round of a scheduled three-round, super-heavyweight Golden Gloves fight Saturday in East Grand Forks, Minn.

Moen's uncle, Mike Sweeney, says the family learned this week that Moen had "serious trauma'' to his brain from previous injuries, including concussions.

Moen had remained unconscious and in critical condition since the fight.

Sweeney says Moen boxed four years during high school and then returned to the ring last year. He was named a Golden Gloves regional champion last year.
