Varlamov stopped 40 shots Oct. 12 in the Avalanche's 5-1 win at Verizon Center. It was his first game against the Capitals since his trade to the Avalanche on July 1, 2011.
Varlamov said after that game he was so nervous his legs were shaking in the first period.
"I think it's always a nice challenge to play against your ex-team," Avalanche coach Patrick Roy said. "It was the same case for me every time we played Montreal. You always want to do well in those games. It's nothing against your ex-team, it's just the pride that comes into play. You want to perform well and you want to have a strong night. I'm sure he is going to be very focused."
