One of the NFL’s fiercest rivalries has literally taken on new depth. A man buried a Kansas City Chiefs flag near what is expected to be the 50-yard line of the new Raiders stadium going up on the Strip. Chiefs fan Chris Scherzer posted a photo of his friend wearing a white hardhat and dark glasses and holding a red and gold Chiefs banner with the inscription “Chiefs Kingdom” on his Facebook page. The Facebook post read, "Flag buried in dirt, encased in concrete, with a stadium built on top of it. Chiefs 1, Raiders 0. Las Vegas." Scherzer says his friend was at the stadium site when another acquaintance snapped the photo. The plan was to bury the flag where they presumed the 50-yard line would be. The Raiders' Las Vegas stadium is set to be completed by the 2020 season.
