He was taken off the ice on a stretcher during the first period of Game 4 against the Washington Capitals at Wells Fargo Center. The Flyers announced that all tests have come back negative.
Flyers general manager Ron Hextall said in a statement that Laughton is doing well, but he will not travel with the team to Washington for Friday's Game 5. Hextall said that the team will issue an update in the coming days.
Teammates said Thursday they heard from trainer Jim McCrossin that Laughton was walking around and talking at the hospital and was expected to be released.
Flyers coach Dave 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.
