Evander Kane announced Thursday on Twitter that he and his pregnant wife lost their unborn child.
She was just over halfway to term when the baby died.
"I would like to thank everyone who has reached out to my wife and I during this extremely difficult time," Kane wrote. "Over the weekend, our daughter, Eva, at 26 weeks, passed away.
"As expecting parents, this past week has broken us. We've received a ton of support from family and friends, and we truly want to thank them.
"We would also like to thank our Sharks Family for their support, compassion, and allowing me to be with my family during this time. My family and I are heartbroken."
Kane has been out since Feb. 26 without any injury designation.
