SAN LEANDRO, Calif. — Ivan Davis stared stone-faced at the television as the news came down that the Oakland Raiders would be moving to Las Vegas and was asked if he was a fan of the team.

“I used to be,” he responded.

Davis has been a Raiders fan for about a half-century, celebrating Super Bowl titles, enduring long stretches of losing and sticking by them even during a 13-year move to Los Angeles. But the NFL’s 31-1 vote Monday to approve owner Mark Davis’ application to move the team to Las Vegas will be the straw that ends his support.

“All the Raiders fans my age, no way you can do it,” he said. “Anyone who lived through the first one will not support them. The older Raiders fans, you lost them forever. The ones who gave their life blood to you, you lost them forever.”
