Nike, a top partner of the NFL, suffered a devastating blow as it lost $28 billion in shareholder value in just one day due to an announcement of expected sales decline. This marked the worst day for Nike shares since its inception in 1980. The company has also cut two percent of its workforce to reduce costs. Since 2012, Nike has been the exclusive apparel provider for the NFL, influencing the league's uniform designs. However, recent decisions by CEO John Donahoe have caused backlash, leading to financial struggles for the company. As the NFL faces a $14 billion loss in court, Nike's future with the league hangs in the balance. With significant changes at the top of the company, including a potential CEO replacement, Nike's fate remains uncertain despite its deal with the NFL running through 2028.
