With the expected announcement that Marc Savard will be placed on LTIR by the Bruins and be lost for the season less than an hour away, many Bruins fans are already plotting the team’s attempts to replace their top-line center.

CapGeek.com today Tweeted the following message to clear up any questions people have about the salary cap and how much room placing Savard on LTIR will give the Bruins:

If the Bruins put Marc Savard on LTIR, they’d be able to add a cap hit of approximately $4 million. That might sound great, but this situation puts the Bruins at high risk of incurring a bonus overage that will carry into 2011-12. Those bonus overages are really going to sting teams because the 7.5 percent cushion is gone in 2011-12.

The 7.5 percent cushion is how much over the cap the team can be including potential performance bonuses, which only count hard against the cap once they are achieved. Right now, the Bruins have Tyler Seguin, Mark Recchi and Steven Kampfer on deals that include performance bonuses.

So if the Bruins use the full $4 million to add a replacement, they will almost definitely incur a penalty next season.
