Dermott didn't play Saturday versus the Red Wings due to a stomach illness, David Alter of The Hockey News reports.
A stomach bug has been running through some of the Leafs' skaters, and Dermott wasn't feeling well enough to play Saturday. The 25-year-old blueliner will aim to recover in time for Monday's game versus the Capitals. Rasmus Sandin and Ilya Lyubushkin handled the third-pairing duties with Dermott out for Saturday's 10-7 goalfest of a win over the Wings.
