If the team's cap room is larger than the injured player's cap hit, they may take on as much as their cap room; however, the injured player may not return to play until the team is again compliant with the original cap.
The MLS rules are not as clear but their wording can be interpreted to mean something similar, it is the most logical way to handle LIR. Though I could understand if the slary stays on the books because an MLS team doesn't have the mechanism of freeing cap space to accomodate return of injured player (at any point in the season) like an NHL team does through sending a player to the minors.
