The 49ers have signed former Cardinals and Texans receiver Christian Kirk to a one-year, $6 million contract as they prepare for life without Brandon Aiyuk. The team is seeking to void AiyUK's guaranteed money so they can release him from his contract more easily and avoid a significant dead cap hit. Aiyuko's position on the 49ers roster could limit his options if he is released. Richard Sherman, a former 49er under head coach Kyle Shanahan, suggested that he should be traded instead of outright released. The 49ers’ receiver room now includes Kirk, Mike Evans, Ricky Pearsall, and DeMarcus Robinson.
