TSN 1050's Jonas Siegel is reporting that James Reimer will be out a minimum of one week with a strained MCL. This certainly beats a tear or a more serious injury although it could take time for him to get back in game shape after he's healed.

I'd expect the Leafs to call up Jussi Rynnas to be Ben Scrivens' backup, though I'd bet we'll see Scrivens in net for the next three Leafs' starts this week.
