Former Las Vegas Raiders team President Dan Ventrelle made a stunning allegation Friday, saying he was let go by the organization for raising concerns about a "hostile work environment."

Raiders owner Mark Davis announced the stunning news Ventrelle was no longer in the front office but no details were released about the decision.

Ventrelle made his remarks in a statement to the Las Vegas Review-Journal.

"When Mark was confronted about these issues, he was dismissive and did not demonstrate the warranted level of concern," Ventrelle said. "Given this, I informed the NFL of these issues and of Mark's unacceptable response. Soon thereafter, I was fired in retaliation for raising these concerns. I firmly stand by my decision to elevate these issues to protect the organization and its female employees."

NFL spokesman Brian McCarthy said the league "recently became aware of these allegations and take them very seriously. We will promptly look into the matter."

Las Vegas removed the interim tag from Ventrelle’s title in January. He took over as team president in July after Mark Badain resigned. Ventrelle was team president as the Raiders navigated a tumultuous few months that saw multiple players arrested, prized young receiver Henry Ruggs III being involved in a deadly car crash and Jon Gruden getting fired over offensive emails.
