Elias did not return to the game and coach Peter DeBoer said afterward the team would know more about his condition Wednesday.
"It wasn't precautionary (leaving him out of the game)," DeBoer said. "I don't think it was an option to have him back. But I don't know anything more than that; I won't until tomorrow morning."
Elias was not available to the media, but captain Bryce Salvador seemed optimistic Elias would be OK.
"I saw him walking around and stuff like that, so I don't think it's too bad," Salvador told The Record. "Hopefully it's a couple days here and maybe he's skating and he's ready to go."
Elias appeared to lose his balance as a result of the hit by Glass and crashed into the boards. He stayed down for some time before eventually getting up and leaving the ice under his own power.
The 37-year-old has seven goals and 25 points in 33 games this season.
"Patrik is a big part of our team," Martin Brodeur told MSG Network. "... Leadership, offensively, defensively, minutes that other people will have to jump in if he does miss extended time."
