"On Thursday, May 25, Ryan Johansen was treated for an acute compartment syndrome of the left thigh. Rapid diagnosis and treatment are critical to prevent complications," Predators general manager David Poile said in a statement Sunday. "His symptoms developed shortly after the end of Game 4 in Nashville, and as they progressed, he was diagnosed, transported to Vanderbilt University Medical Center and had surgery performed by head team physician Dr. Jed Kuhn within two hours of his diagnosis.
"As a result, he had no permanent injury to his muscle, nerves or blood vessels and we expect a full and complete recovery. The Predators would like to thank Vanderbilt Life Flight Paramedics, the VUMC Emergency Department, Operating Room Nurses, and Anesthesiologists for their expedient and excellent care."
The Predators announced on Friday that Johansen would miss the remainder of the 2017 Stanley Cup Playoffs, but didn't provide details of his injury.
Johansen tied for the Predators lead during the regular season with 61 points (14 goals, 47 assists). He is tied for the Predators lead in the playoffs with 13 points (three goals, 10 assists) in 14 games.
Johansen skated slowly to the bench after being checked into the boards by Ducks defenseman Josh Manson at 15:22 of the second period in Game 4. He returned to the game and fell awkwardly after a hit by Ducks defenseman Hampus Lindholm with 4:38 left in the third period.
The Predators won Game 5 by a 3-1 score on Saturday without Johansen to take a 3-2 lead in the best-of-7 series. Game 6 is in Nashville on Monday (8 p.m. ET; NBCSN, CBC, TVA Sports).
