A jury in Oklahoma has convicted LeShon Johnson, a former N.F.L. running back, on dogfighting charges in a sprawling federal case that the authorities said could bring a hefty prison sentence and fines.
In October, federal agents seized 190 pit-bull-type dogs from Mr. Johnson, 54, of Broken Arrow, Okla., the most ever taken from a single person in a federal case, according to the Justice Department, which announced on Tuesday that a verdict had been reached in the case.
After a five-day trial in U.S. District Court in Muskogee, Okla., jurors on Friday found Mr. Johnson guilty on six of the 23 counts that he had been charged with for his role in running what investigators described as a major dogfighting kennel.
