According to Sportsnet's Elliotte Friedman, the League and the Players Association are working on putting together a COVID roster protection plan. The plan is expected to include optional taxi squads and emergency call-ups from the AHL.
If this roster protection plan is implemented, it will go a long way in making sure that teams will be able to ice the appropriate number of players, rather than being forced to play shorthanded. This could certainly help to prevent injuries as well, with players not being forced to play more than a healthy amount.
