In a move that at least I myself found somewhat surprising, among the steps that the Pittsburgh Steelers took yesterday to get down to 75 men on their roster was to revert fourth-year offensive tackle Mike Adams from the Active PUP List to the Reserve PUP List, which carries over into the regular season.
As the immediate implication of this move, Adams will not be able to practice or play for the first six weeks of the regular season, and will be eligible to return only after that point. Even if his recovery lasts a couple of weeks into the season, this would still represent an extreme move to be without, ostensibly, your top swing tackle if he could return sooner than six weeks.
