The injury occurred in Trouba's second game back from a lower-body injury that had kept him out for 20 games. He had recorded two assists in his return, a 6-2 Jets victory over the Chicago Blackhawks on Thursday.
Trouba had played 14:20 with two hits and two blocks before the injury occurred.
"You don't get diagnosed with a concussion post-game. They'll keep you out of a game for concussion symptoms, and they'll list all of them. But you need to go see a doctor or specialist that handles that," said Maurice. "Then they'll pass down 'yes we believe he has a concussion.' That's where we believe it's at. We just don't have final confirmation on that.
"From that it just progresses too a point where he can get on the bike, push himself real hard. If there's no symptoms, you wait the next day, you put him on the ice lightly, and you move through. There's no defined timeline, but there is a procedure you have to go through."
There was a bit more clarity on another defenceman, as Dmitry Kulikov has elected to not have back surgery, and will instead go through alternative treatment methods.
The surgery route would have kept Kulikov out of the line-up for at least eight weeks. Now the timeline looks more like three-to-four weeks.
"When he met for his final consult, it's the player's choice with what he wants to do. He's going to forego surgery. There are other remedies with this," Maurice said of the injury, which he classified as a re-occurrence of what ailed the 27-year-old in Buffalo last season.
"It's one of two options in how to treat the injury. He's been through it before, so he understands it very well. But it's not a definite thing that he needs to have surgery on it," said Maurice.
"Hopefully everything settles down, heals, and he's a player for us sooner."
