Pittsburgh Penguins defenseman Kris Letang is out indefinitely after suffering a stroke on Monday, the team announced.
Letang also suffered a stroke in 2014 and missed about two months of the season before returning in time for the playoffs.
The Penguins announced the 35-year-old is "not experiencing any lasting effects" from the latest stroke.
"Kris reported symptoms to the training staff on Monday and was immediately taken to the hospital for testing," General Manager Ron Hextall said in a statement. "The test results were shocking to hear, but we are grateful that Kris is doing well.
