Dan Ventrelle alleges he was fired as team president of the Las Vegas Raiders in retaliation for bringing concerns by multiple employees about hostile workplace conditions within the organization to the NFL.

"I take that responsibility very seriously, which is why multiple written complaints from employees that Mark [Davis] created a hostile work environment and engaged in other potential misconduct caused me grave concern," Ventrelle said 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.

"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."

The Raiders did not say why Ventrelle was let go when they announced his departure earlier Friday. They had no comment on Ventrelle's statement.
