Trouba was attempting to chase down a dump-in behind the St. Louis net and appeared to get his skate tangled up with Blues defenseman Jordan Leopold. Trouba then fell face-first into the boards and remained on the ice for several minutes.
He was seen moving his arms and gave Jets fans a thumbs up as he was removed from the ice.
Jets coach Claude Noel offered an update on Trouba after the game, which the Jets won, 4-3, in a shootout.
"Trouba is still getting evaluated but he's good. He's just getting tested but I think everything's fine." - Noel on Trouba— Winnipeg Jets (@NHLJets) October 19, 2013
Friday was Trouba's eighth game in the NHL after the Jets drafted him in the first round of the 2012 draft. So far in his career he has scored one goal to go with one assist.
Earlier this week San Jose Sharks defenseman Dan Boyle had to leave on a stretcher following a hit from Maxim Lapierre, a play that resulted in a five-game suspension. On Thursday night Detroit's Niklas Kronwall was on the receiving end of a similar hit from Cody McLeod who is awaiting an in-person hearing with the NHL next week.
