Jon Gruden is unlikely to get another chance to coach an NFL team following the disclosure that he sent sexist, racist and homophobic emails, sports marketing experts said.

Gruden resigned as coach of the Las Vegas Raiders on Monday after The New York Times reported he used misogynistic and anti-gay language in numerous emails during a seven-year period dating back to 2010.

According to the Times, he used a racial trope to describe NFL Players Association Executive Director DeMaurice Smith, mocked the drafting of a gay player in 2014, the hiring of women referees and tolerance for player protests aimed at promoting racial justice.
