Thompson exited Monday’s game against Montreal with a lower-body injury following his first shift of the second period. Luukkonen played the first two periods of that game but was replaced by Devon Levi to start the third due to an ailment he had sustained in practice.

Tage Thompson and Ukko-Pekka Luukkonen’s injuries aren’t as bad as some had feared. Both missed practice on Wednesday as well as Mattias Samuelsson and Lindy Ruff said, “Tage and ‘Uppie” are both day-to-day and both are possibilities for Thursday,

Buffalo Sabres coach Lindy Ruff says defenseman Mattias Samuelsson is out indefinitely with a lower-body injury. Ruff called the severity of the injury “pretty strong."
