Red flags and sideline replay booths are here to stay—at least for the next five years. The NFL voted to keep instant replay for five more seasons at the annual owners’ meetings on Tuesday. The measure passed 29-3; the Chiefs were one of the three teams voting against it, along with the Colts and Bengals. Instant replay was reinstated in 1999. One change has been made to the previous system. Teams that successfully use two challenges will be given an extra challenge. Before the change, teams were allowed just two challenges, except for the last two minutes of each half, when a replay official could order a review. …The Chief signed free agent defensive tackle Lionel Dalton from the Redskins. He had 14 tackles and a sack last year. He spent 2002 with the Broncos and the previous four years before that with the Ravens. He was a member of Baltimore’s championship team in Super Bowl XXXV.
