The Chicago Blackhawks will not wear Pride-themed warmup jerseys before Sunday’s Pride Night game against Vancouver, a person with knowledge of the matter told The Associated Press, because of security concerns involving the law that Russian President Vladimir Putin signed in December that expands restrictions on activities seen as promoting LGBTQ rights.

The decision was made by the NHL following discussions with security officials within and outside the franchise, according to a person familiar with the situation who spoke to the AP on Wednesday on condition of anonymity because of the sensitivity of the move.

The league declined to comment through a spokesperson, as did agent Dan Milstein, who represents Russian players on the Blackhawks and other teams.

Chicago coach Luke Richardson he and his players were disappointed in the decision.
