The Chicago Blackhawks will not wear Pride-themed warmup jerseys before Sunday's Pride Night game against the visiting Vancouver Canucks because of security concerns involving a Russian law that expands restrictions on activities seen as promoting LGBTQIA+ rights in the country.

The decision was made by the NHL organization 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.
