If the injury is a lingering injury that keeps him out a few months, say 3 months, it gives enough time and cap space to trade for say;
Miere and Karlsson with 50% retention. And still have cap space to add JT Miller with 50% retention this year with Schenn.
That would be a stout improvement for the playoffs.
I don't know what could be offered the other way but there would be some heavy lifting at the draft and summer.
But what a 3rd line
Meire (48 pts) , Miller (42 pts) with Kerfoot/Bunting ?
A 2nd group PP with Karlsson on the point
And a defensive stalwart and protector is Schenn.
And still have some space if a contract is moved.
