Buffalo Sabres captain Jack Eichel will miss an additional week at minimum, head coach Ralph Krueger said after Tuesday's loss to the Philadelphia Flyers, according to The Athletic's John Vogl.

Eichel did not suit up Tuesday due to an upper-body injury. Krueger said the star forward returned to Buffalo early, and he will still need further evaluation.

It's unclear when exactly Eichel suffered the injury, but he did appear to experience discomfort in his neck late in Sunday's loss to the New York Islanders.

Eichel missed two games earlier this season due to a lower-body injury. The 24-year-old hasn't put up his usual point totals to this point of the season, registering just two goals and 16 assists in 21 contests.

The Sabres are in last place in the NHL with six wins through 24 games.
