The Disabled List screen (Team Menu >> Transaction section >> Disabled List) is where you can manage your disabled list:

The Disabled List screen behaves very similarly to the Overview screen, except that by default, only two boxes of players are listed, with the team's disabled list on the right. As with that page, to make a transaction, drag a player from one pane to another, or right-click on a player and select a transaction from the right-click menu.

In the Disabled List box, players above the dividing space are on the major league disabled list, and those below the dividing space are on the minor league disabled list.

The Transaction Legend and Action Menus are both identical to those described on the Overview screen, as is the link to the Minor League System Report.
