Las Vegas Raiders president Marc Badain, who started with the team as a training camp intern in 1991 and served a central role in the team's move from Oakland to Southern Nevada last year, has resigned.

The move was met with shock in the organization, while Badain, 51, simply said it was time for him to "focus on my family and look ahead to new pursuits."

"The successful construction and operation of Allegiant Stadium has been unequivocally the most challenging part of my 30 years with the organization," Badain said. "Seeing it through to the end has been rewarding beyond measure. Together the Raiders and Las Vegas accomplished what seemed impossible.

"I am forever grateful to [Mark Davis] for his unwavering support and friendship. I wish him and the Raider family the best. I will always feel a part of the team because everyone knows...Once A Raider Always A Raider."

Dan Ventrelle, the team's executive vice president and general counsel, will assume the role of team president.
