Versteeg, who sustained an upper-body injury in Tuesday's 6-5 overtime loss against the Washington Capitals, did not take part in the team's morning skate. Versteeg also didn't take part in Monday's practice and coach Kevin Dineen said he was day-to-day.
Versteeg was injured when he absorbed a hard check into the boards from Alex Ovechkin 1:13 into Tuesday's game. Versteeg stayed on the ice for a couple of minutes and left the bench area, but returned shortly thereafter.
On his first shift back, Versteeg cross-checked Ovechkin near center ice and the two scuffled.
Versteeg finished the game, ending with 13:38 of ice time.
It's the second injury setback this season for Versteeg, who missed the first five games after sustaining a lower-body injury the day before the season opener.
Versteeg has one goal and two assists in six games after finishing third on the team with 54 points last season.
