PHILADELPHIA -- Philadelphia Flyers forward Scott Laughton remained hospitalized Thursday after he was taken off the ice on a stretcher during the first period of Game 4 against the Washington Capitals on Wednesday night at Wells Fargo Center.
Laughton was transported to Jefferson Hospital, where he stayed overnight. The Flyers announced that all tests have come back negative.
"No update from what we released last night," said Flyers coach Dave Hakstol, who added he didn't know if Laughton would be released from the hospital Thursday. "I don't. I don't have any further update on it. I'm waiting for an update."
Hakstol said he had not spoken with Laughton since the injury.
With 3 minutes, 49 seconds left in the period and the Flyers leading 1-0, Laughton was racing for the puck in the offensive zone with Capitals defenseman John Carlson. After the two made contact a few feet from the boards, Laughton went crashing horizontally and back-first at full speed into the end wall. His body flipped over, and he lay motionless and face down for several minutes behind the Washington net. He briefly moved his legs and arms before a trainer tended to him.
"It's just one of those plays where we're kind of even and he tries to stick-handle through me and take it to the net," Carlson said. "I'm just trying to defend him."
EMT members quickly brought out the stretcher, and it appeared Laughton was talking with them before he was taken off the ice. As he was taken off the ice, fans gave him a standing ovation and began to chant, "Let's go, Flyers."
"Your first thought is always concern for the player, for your teammate," Hakstol said after the game. "It's never a sight you want to see. Thoughts right now are just, we don't know a whole lot more than you guys know, but hopefully Scotty will be fine."
An Ontario native, Laughton, 21, captained Team Canada's world junior team in January 2014 and was playing in only his third Stanley Cup playoff game. He played 71 games for the Flyers during the regular season and scored seven goals and 14 assists for 21 points.
The Flyers won 2-1 on Wednesday, but they trail the Capitals 3-1 in the best-of-seven series. Game 5 is Friday night in Washington, D.C.
