The St. Louis Blues forwards Jaden Schwartz and Nail Yakupov each are questionable to play in the Winter Classic with an illness. "We're hoping both Schwartz and [Yakupov] make it in tomorrow," coach Ken Hitchcock said after practice Sunday, "but yeah, we've had this for eight days now and it's been tough for everybody, coaches included. We've all had a tough go with this, but for those guys not to be able to be here, both were not well this morning at all. For both of them not to be able to attend this skate and everything, you can see how sick they are." The Blues will be playing in their first outdoor game and have lost six of their past nine games (3-5-1). "Aside from all this hype, being outside and all that, it's a big game for us against the division team," left wing Robby Fabbri said. "We've got to start stringing some wins together here in the second half, and we've got to start with this one." Defensemen Jay Bouwmeester [2011 NHL Heritage Classic], Robert Bortuzzo [2014 NHL Stadium Series] and Carl Gunnarsson [2014 Winter Classic] are the only Blues players with outdoor-game experience.
