Gordie Howe is "comfortable and happy" after he received a second stem-cell treatment at a clinic in Mexico on Monday, The Hockey News reported.
Howe, 87, had a series of strokes in 2014, including a major one in October.
"Our dad continues to participate in a clinical trial where stem cells are being used in the treatment of a stroke," son Murray Howe told The Hockey News. "We'd like to wait until the first phase of that clinical trial is complete before providing any more updates. At this time, our dad is comfortable and happy. That remains our goal. We want to thank everyone for their ongoing support for Mr. Hockey."
The Howe family said it believes the first stem-cell treatment, also at the Novastem clinic in Tijuana on Dec. 8, not only saved their father's life but has allowed him to enjoy it.
"It's not just laying around and doing nothing," son Mark Howe told the Detroit Red Wings website in March after a day spent fishing. "He can experience the fun things that he's done his whole life, obviously to a different extent, but there is some quality to his life now."
The report said the plan is for Gordie Howe "to go back to Michigan for a short time, then he will move to a nursing home in Ohio that specializes in treating people with dementia."
A member of the Hockey Hall of Fame, Gordie Howe played 25 seasons with the Red Wings and helped them win four Stanley Cup championships. He scored 801 goals and 1,850 points in 1,767 regular-season games covering 26 NHL seasons.
