The Coyotes defeated the Blues 4-3 on Thursday in St. Louis after losing to them 4-3 on Tuesday.
"It's a big challenge," Arizona coach Rick Tocchet said. "As an athlete, you're looking for challenges. These are some big moments to see if guys rise up, right? Tough team to play against. They beat us the first, we beat them the second, and they're going to be coming the next game. We've just got to be ready for these challenges."
Arizona was scheduled to play the Minnesota Wild on Saturday and Sunday, when St. Louis was scheduled to play the Colorado Avalanche.
Wild games are postponed through Feb. 9, and Avalanche games are postponed through Feb. 11 due to COVID-19 protocol issues with each team.
The next two Coyotes-Blues games were rescheduled from March 29 and 31.
"It's out of our control, so we adapt and deal with whatever is set in place for us," St. Louis forward Mike Hoffman said. "We'll practice tomorrow and get ourselves back and start getting ready for the next game."
The NHL has postponed 24 games during the 2020-21 season; two were postponed prior to its start.
