Sanderson was limited to 12:52 time-on-ice in Saturday's 7-4 win over the Seattle Kraken, exiting with an undisclosed injury, and, after undergoing further testing, has been ruled out on a week-to-week basis. The 23-year-old Sanderson has been held off the scoresheet in three straight games, but has 48 points (11G / 37A) in 62 games this season and will be sorely missed by a surging Senators' team that makes a late-season playoff push. With Sanderson sidelined, expect Thomas Chabot to take his spot on the team's top powerplay unit.
