Washington Capitals star defenseman John Carlson will celebrate his day with the Stanley Cup at a July 4 fundraiser in Bethesda, according to an Instagram story created by his wife, Gina Carlson.

The NHL has a long-held tradition that enables players who win the Stanley Cup that year to spend a private day with it during the summer as they see fit. The Capitals beat the Las Vegas Golden Knights earlier this month to win the Cup.    

It’s not yet clear exactly where the fundraiser will take place, but it will be held to benefit Defeat DIPG—a Bethesda organization that was created to raise money to research treatments for DIPG, a condition that causes brain tumors to develop in children.

Defeat DIPG was founded by Mark and Jenny Mosier after the death of their 6-year-old son, Michael Mosier, from the disease in May 2015, according to the organization’s website.

Gina Carlson’s post indicated the organization would have more details about the fundraiser with the Capitals star and asked any restaurant in Bethesda interested in participating to contact the organization. On its Instagram account, @defeatdipg, the organization wrote “there is super exciting news” and urged Caps fans to “stay tuned” and “save the date for July 4!” on a picture featuring the Stanley Cup.

John Carlson announced over the weekend he would sign an 8-year, $64 million extension to stay with the Capitals long-term. Carlson and his wife bought a $3.4 million home in Chevy Chase in 2015, according to Washingtonian.
