The San Francisco 49ers and Las Vegas Raiders held a joint practice and are set to face each other in a preseason game at Allegiant Stadium. The joint practice, conducted in the Nevada desert heat reaching 98 degrees, featured strong offensive performances from both teams, with the 49ers' offense notably excelling while their defense struggled. Key 49ers players such as quarterback Brock Purdy and tight end George Kittle participated actively, with Purdy expected to start in the upcoming preseason game. The 49ers' defense will be without several expected defensive backs including Renardo Green, Upton Stout, Jason Pinnock, and Richie Grant, as well as linebacker Fred Warner and defensive end Nick Bosa, who was absent from the joint practice due to neck soreness but participated in pregame workouts. Offensive lineman Trent Williams also did not warm up with the team. Raiders coach Pete Carroll indicated that his starters would receive extended playing time in the preseason game. The 49ers aim to play several first-stringers, including Purdy, in the game. The game coverage is scheduled to begin at 1 p.m. on FOX5 Vegas.
