(CBS4) – More sports fans are warming up the idea of attending games indoors, according to a recent poll from Morning Consult. In the poll, 48 percent of U.S. adults who regularly attend sporting events say they would be comfortable going to a game inside a half-full indoor venue. 72 percent of regular event-goers would be comfortable if facilities required fans to wear masks.

The numbers are important for both the NBA and NHL as they hold their games indoors and would want to open their arenas to fans once their next season begins. Neither league has announced a start date, so the Denver Nuggets and Colorado Avalanche are currently in limbo, but Ball Arena will be used as a voting center for the upcoming election.

The Denver Broncos currently have a cap of 5,700 fans attending their games at Empower Field at Mile High and the Colorado Rapids will have 1,165 fans at Dick’s Sports Goods Park for their remaining games.
