The San Francisco 49ers, led by quarterback Brock Purdy, are preparing for their preseason finale against the Las Vegas Raiders, aiming to improve after a disappointing outing against the Saints. Coach Kyle Shanahan has confirmed that several starters, including Deebo Samuel and George Kittle, will play, although All-Pro running back Christian McCaffrey will miss the game due to a calf injury. The team is also dealing with contract disputes involving key players Trent Williams and Brandon Aiyuk, creating uncertainty ahead of the regular season. Meanwhile, the Seattle Seahawks are also set to field most of their starters, including Geno Smith, in their preseason finale against the Cleveland Browns, providing them a chance to gain momentum before the season begins. Coach Mike Macdonald emphasized the importance of live game action for his starters, despite some notable absences due to injuries. Both teams are looking to finalize preparations and address lingering issues before the start of the regular season.
