That's definitely not my understanding of it...
There is no limit to how many players a team can place on the Injured Reserve at any one point. However, players on the Injured Reserve still count against the salary cap Upper Limit. If a team runs out of cap space because of recalled players while another player is dealing with a long term injury, the team has the option of invoking the Long Term Injury/Illness Exception, or LTIR, to fit more players under the cap.
50.10 Player Injuries, Illnesses and Suspensions.
(a) All Player Salary and Bonuses paid to Players on an NHL Active Roster, Injured
Reserve or Non-Roster that are Unfit to Play – being either injured or suffering from an illness –
shall be counted against a Club's Upper Limit, Actual Club Salary and Averaged Club Salary, as
well as against the Players' Share. Notwithstanding the preceding sentence, a Club shall be
permitted to exceed the Upper Limit (but League-wide Player Compensation shall never be
permitted to exceed the Players' Share) by virtue of the Bona-Fide Long-Term Injury/Illness
Exception set forth in subsection (d) below.
Then you put them on LTIR for the 10 days lol.
