Predators forward Ryan Johansen, who has been ruled out for the remainder of the playoffs after undergoing thigh surgery, was diagnosed with acute compartment syndrome, according to Jon Morosi of NHL Network and FOX Sports.

Acute compartment syndrome occurs when excessive pressure builds up inside an enclosed muscle space in the body. It usually results from bleeding or swelling after an injury. It can be limb and life-threatening.

Morosi added that Johansen is doing well and is expected to recover fully.

The Predators have yet to confirm.
