Waived/Injured for non-guaranteed contracts before the season starts

If a player is injured in OTAs, minicamp, or training camp, and is waived/injured, is the team responsible for a negotiated amount of a non-guaranteed contract?

So, if a player has a $5m non-guaranteed contract and suffers an ACL before the season starts and is out for the year, does the team have to pay the full salary? If so, why would a team waive/injure instead of putting a player on injured reserve (IR) if they have an injury that knocks them out for the season?
