Kucherov suffered an injury on a high-stick from Zdeno Chara in the first period that cut his face. He left to the locker room after the incident but briefly returned for a couple of shifts in the second period before he removed himself from the game.
His final shift came with seven minutes remaining in the second.
After the game, head coach Jon Cooper said he’ll have more of an update on Kucherov Tuesday but that he was “hopeful” it wouldn’t be a long-term injury.
“He did come back afterwards and played for a little bit so obviously we’re hopeful and maybe I don’t know, hope we get a little bit of a break here so we can rest our guys including him,” Cooper said.
The Lightning will now await the winner of a series between the Flyers and Islanders, which New York currently leads 3-1. Game 5 in that series is scheduled for Tuesday.
The Lightning have already played the entire post-season without Steven Stamkos but losing Kucherov long-term would be significant. The 2018-19 Hart Trophy winner has been on fire in the post-season, scoring 16 points in 12 games.
