The San Francisco 49ers and Las Vegas Raiders conducted a joint training practice in Las Vegas, where temperatures reached 98 degrees. The session featured notable offensive plays from both teams, though the 49ers' defensive line struggled against the Raiders' offensive line. Key absences for the 49ers included defensive end Nick Bosa due to soreness and a skeleton defensive line overall. Running back Christian McCaffrey was highlighted by coach Kyle Shanahan as being in top form, described as "fast as he's ever been," and quarterback Brock Purdy was praised for his mental sharpness. Tight end George Kittle was active and productive during the practice. The 49ers made roster adjustments by signing defensive lineman Shakel Brown to bolster an injury-affected defensive line and releasing tight end Ross Dwelley. Brown had been with the team the previous season, and Dwelley’s release was seen as a move to balance roster depth, with the possibility of his return. Undrafted lineman Sebastian Valdez, nicknamed "The Hulk" and coached by Bill Belichick, has drawn attention for his focused effort to make the team. Raiders coach Pete Carroll announced that his starters would receive extended playing time in their upcoming preseason game against the 49ers at Allegiant Stadium. The Raiders are nearing the end of their training camp as they prepare for the regular season opener on September 7 against the New England Patriots.
