Some players seem to have "disappeared". e.g., Brewers' Dave Nilsson. He is still listed on my RT roster, as "Uncarded" (whatever that means!). I cannot find him on the Brewers' roster or any other info on him. Same for a half-dozen other players. Anyone know if these guys are still in the majors and how do we find out? Or should they be dropped when 27-roster set up?
