Buffalo Sabres superstar Jack Eichel left Saturday's clash against the Boston Bruins in the first period after appearing to hurt his right ankle during an awkward fall.
There was no update on Eichel's status after the game.
The former second overall pick has 22 goals and 31 assists over 54 games in 2017-18, his third season in the NHL.
Eichel, 21, missed 21 games last season with a sprained left ankle.
Buffalo would go on to beat Boston 4-2.
