If Page has yet to sign his tender offer before OTAs begin, he would sign an injury protection waiver if he were to participate in workouts. Such waivers typically guarantee his 2010 salary in the event of an injury incurred while participating in a team activity. He’s also under no obligation to sign a waiver and participate should he choose not to do so. Both the team and player have options in Page’s scenario.
Once the Chiefs officially sign their 81st player to a contract, a one-for-one swap would have to occur on the roster (this typically happens when draft picks sign just prior to the beginning training camp), but until then the team can carry more than 80 as long as those picks remain unsigned.
