Dillon (undisclosed) is slated to play against Dallas on Wednesday, per Mike Morreale of NHL.com.
Dillon missed the third period of Monday's 5-3 loss to Columbus for precautionary reasons, but it seems he won't miss a full game due to the issue. He has three goals, nine points, 24 PIM, 65 hits and 42 blocks in 26 outings this year.
