"They're both banged up, like a lot of guys on our team," Hitchcock said after neither St. Louis forward took part in the team's morning skate at Canadian Tire Centre.
Schwartz and Sobotka played Saturday in the Blues' 4-3 overtime win against the Columbus Blue Jackets that began their two-game road trip.
"We went the other way against Columbus and neither guy was effective in the tail end of the game," Hitchcock said. "It's not starting the game, it's finishing the game. And for us, if we feel like we want them to finish the game, then we're going to have to give them as much rest as we can so that they're ready to go, so we opted not to skate them [Monday]."
"Quite frankly we weren't playing very good," Hitchcock said. "We weren't playing very good defensively and we needed to make some adjustments."
Both were chosen by Tampa Bay at the 2013 NHL Draft -- Drouin of the Halifax Mooseheads was selected in the first round (No. 3) and Erne of the Quebec Remparts in the second (No. 33). They also were roommates in Tampa Bay during development camp prior to the season.
Until that time arrives, however, they play for different teams in the Quebec Major Junior Hockey League and likely will oppose each other at the 2014 IIHF World Junior Championship in Sweden.
Erne is taking part in the United States National Junior Team selection camp this week on the campus of the University of Minnesota while Drouin is at Canada's selection camp.
Drouin's participation at the WJC is dependent on his health as he is still recovering from a concussion he sustained after taking a hit from Erne while in a vulnerable position along the boards in the first period of a regular-season game earlier this month.
"Getting the legs going is probably the biggest thing, hopefully feeling the puck early on and putting the puck in their zone," Kane said. "Getting on the forecheck and getting some scoring opportunities is what I'm trying to do the first period."
Kane had seven goals and seven assists in 26 games before the injury. The Jets (14-15-5) went 2-3-1 in his absence.
"It will be good to get him back in the game," Winnipeg coach Claude Noel said. "He just needs to get himself going the best he can. How much he'll play is to be determined by different factors. He's a guy that can have an impact on the game and create some offense."
PITTSBURGH -- The largest set of injuries the Pittsburgh Penguins have faced this season will lead to a nearly unrecognizable Pittsburgh lineup against the Toronto Maple Leafs on Monday (7 p.m. ET, NHLN-US).
Forward Evgeni Malkin, who sustained a lower-body injury against the Detroit Red Wings on Saturday, is day-to-day and will not play Monday, according to coach Dan Bylsma. He also said defenseman Kris Letang has been placed on injured reserve with an upper-body injury.
Sidney Crosby said his team will need to play at its best to compensate for the injuries.
"I think you want to make sure you're at your best," Crosby said. "I think that's always the case but I think it's pretty natural when guys are missing for everyone to want to pick it up a little bit more and find ways when guys are out."
Four games on the NHL schedule get the week started and NHL Live with Bill Pidto and E.J. Hradek, at 5 p.m. ET Monday on NHL Network, will have you covered. Steve Mears will be in Minnesota with Dave Starman for the latest from the U.S. selection camp for the upcoming IIHF World Junior Championship.
In the latest segment of Behind the Bench with Barry Melrose, our NHL analyst will discuss the best and worst coaching moves of the week.
Defenseman Philip Samuelsson, a second-round pick of the Pittsburgh Penguins in the 2009 NHL Draft and son of two-time Stanley Cup winner Ulf Samuelsson, was recalled by the team Monday from Wilkes-Barre/Scranton of the American Hockey League.
Samuelsson has six assists, a plus-3 rating and 35 penalty minutes in 26 AHL games this season. The Penguins are battling numerous injuries on their blue line that have sidelined Kris Letang, Brooks Orpik, Rob Scuderi and Paul Martin.
So it was disappointing to lose my last game for Plymouth [against the Peterborough Petes] before flying to Minnesota to begin U.S. selection camp Sunday afternoon. Overall, the trip over wasn't too bad, it was a quick flight. The one-hour time change saved me an hour so I didn't lose too much during the day. I got to the rink right away and kind of sat around for a little bit; I felt good really all day and wasn't too tired. I had to wake up early since I forgot to pack [Saturday night] so maybe that's why my eyes are a little bloodshot.
I'll be rooming with forward [Tyler] Motte at the hotel. At the National Team Development Program, I knew him well and worked out and skated with him over the last part during my time with the program.
Once I got on the ice [at Mariucci Arena], I felt good. The legs felt good and everyone looked pretty fast out there so it was good.

It's a big milestone for me and I'm happy to help my team with lots of good teammates. It's fun.
