Devils' Hughes day-to-day after getting hit along boards
Ruff added that Hughes will be further evaluated on Wednesday.
Hughes was rubbed out along the boards by Jeremy Lauzon late in the opening frame. The 2019 No. 1 overall pick was favoring his upper body as he left the ice and didn't return.
Hughes scored two goals in the Devils' opener on Friday and already recorded an assist during Tuesday's first period. He finished second on the team with 31 points in 56 games a year ago.
