The Chicago Bears have acquired star pass rusher Khalil Mack from the Raiders on Saturday, Sept. 1, 2018, in a massive trade that sends two first-round draft picks to Oakland. A person with direct knowledge of the trade told The Associated Press that Oakland will get first-round selections in 2019 and 2020, a sixth-rounder next year and a third-rounder in 2020. Oakland also included its second-round selection in 2020. The person spoke on condition of anonymity because the trade had not been announced. (AP Photo/Marcio Jose Sanchez, File)
