It didn't look good from the video, and we now have official word that it wasn't. The Tampa Bay Lightning have released an official update on defenceman Mikhail Sergachev after he was stretchered off the ice in last night's game against the New York Rangers.
With this type of surgery, it usually takes 10 to 12 weeks before it's recommended that you let your leg bear the full weight of your body again. While there's no official word yet, the prospects of Sergachev returning in the regular season are low, and I wouldn't be surprised if he's done until the 2024-25 season.
