A power outage at Navy-Marine Corps Memorial Stadium in Annapolis halted the NHL’s Stadium Series game between the Capitals and Maple Leafs on Saturday Night.

The lights went out at the 10-minute mark in the third period with Washington ahead, 5-2. As with most outdoor games, the teams switch goals midway through the third period so each team has an equal amount of time attacking either direction.

After about 10 minutes, the stadium lights began to flicker on again. It was not immediately clear what caused the outage.

Winter Storm Riley battered the East Coast and caused thousands of power outages in Maryland on Friday.

The delay forced NBC to move the end of the game to NBC Sports Network in favor of local news for most of the country. In the Washington region, however, WRC-4 stayed with the game.

This is a developing story. This post will be updated as more information becomes available.
