Samuelsson (undisclosed) was injured in Tuesday's preseason game versus the Blue Jackets, and he'll be evaluated further Wednesday, Rachel Lenzi of The Buffalo News reports.
Samuelsson was injured on a blocked shot in the second period. The 26-year-old defenseman's status should be updated prior to Thursday's preseason contest against the Red Wings, but expect the Sabres to be cautious with Samuelsson prior to the regular season.
