The Jacksonville Jaguars announced the resignation of the strength coach Chris Doyle on Friday night, not long after an organization that promotes diversity in the N.F.L. called the recent decision to hire Doyle “simply unacceptable.”
Doyle, whose hiring by the Jaguars was announced on Thursday, left the University of Iowa’s football staff last year after a number of current and former Hawkeyes players said he had fostered a culture of bullying and racism.
The Associated Press first reported a statement from Jaguars Coach Urban Meyer saying that Doyle had resigned and that he had accepted the resignation.
