Las Vegas Raiders interim team President Dan Ventrelle has left the organization less than a year after taking over the job.
Owner Mark Davis announced in a Friday that Ventrelle "is no longer with the Raiders organization" but divulged no details around the decision.
Ventrelle said in a that he was fired in retaliation for bringing concerns from multiple employees to the NFL about a "hostile work environment."
"When Mark was confronted about these issues, he was dismissive and did not demonstrate the warranted level of concern," Ventrelle said in the statement. "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."
Davis did not comment on the allegations specifically.
"I've heard about (Ventrelle's) statement, but I won't comment on it," Davis . "The only thing I want made clear is that Dan Ventrelle was never president of the Raiders. He has always been the interim president. He was never named president. The interim was always a temporary designation to determine whether he would be the (full-time) president or not. I want that clear -- he is not the president of the Las Vegas Raiders. Never was. I think there's a misconception about that."
The NFL is looking into Ventrelle's allegations.
"We recently became aware of these allegations and take them very seriously," NFL spokesman Brian McCarthy said in a statement. "We will promptly look into the matter."
Ventrelle joined the Raiders in 2003 and worked his way up to general counsel and executive vice president before taking over as team president on an interim basis last July after Marc Badain resigned.
Ventrelle and Badain played key roles in the Raiders' move from Oakland, California, to Las Vegas.
