Anaheim Ducks forward Patrick Eaves has been diagnosed with Guillain-Barré Syndrome, a rare condition in which the immune system attacks the body through the peripheral nervous system.

Eaves began feeling weak last week and saw doctors soon after. He was admitted to the intensive care unit and was transferred out as his condition stabilized over the weekend, according to a team statement released today.

“I’m determined to fully overcome this and return to the ice as soon as possible,” Eaves said in a statement of his own. Recovery times for Guillain-Barré vary—according to the NIH, a person usually stabilizes at his or her lowest point of weakness or paralysis for a bit of time before beginning to improve, though some level of muscle weakness often persists for weeks or longer, or in some cases, even permanently. The condition can be treated but not cured.

Eaves signed a three-year, $9.45 million contract with the Ducks this summer after being traded from the Stars in February.
