Today, Sheldon Keefe provided a somewhat positive update on Knies' health status. Keefe said that Knies has "improved a lot" but has not skated since the early moments of Game 2. Additionally, Keefe confirmed that Knies is very unlikely to play in Game 5 tomorrow, but given that Game 6 (if necessary) could be on Sunday or even Monday, there is a chance that the extra couple of days could give Knies enough recovery time to at least be upgraded to a game-time decision.
While it does suck that Knies won't be ready to go for Game 5, it's encouraging that Keefe and the Leafs seem to be pleased with how he's recovering. The next step for Knies will be getting back onto the ice for a solo skate. Next, it will be about getting him back on the practice sheet in a non-contact sweater and seeing how he responds before clearing him to return to action without restrictions or limitations.
