Boston Bruins right wing David Pastrnak (undisclosed) is poised to rejoin the lineup on Tuesday against the St. Louis Blues, Lou Korac of NHL.com reports. The Czech superstar has joined his teammates for pregame warmups after initially being regarded as a game-time decision. Pastrnak, who has missed five contests, is once again averaging over a point per game this season, scoring 11 goals and serving 18 assists in 26 appearances. Alex Steeves has seen time on the first line during Pastrnak's absence and must now settle for a lesser role.

Colorado Avalanche goaltender Scott Wedgewood (back) will start on Tuesday night against the Nashville Predators. He has been out of the lineup for three games due to a back issue. This season, Wedgewood ranks in the top four in all the main goalie categories. He has a 13-1-3 record, a 2.07 goals-against average, and a .920 save percentage. Over his last three starts, Wedgewood has allowed three total goals, recording his first shutout of the season against the Chicago Blackhawks on Nov. 23. On Tuesday night, Wedgewood faces the NHL's fourth-weakest offense, as Nashville is averaging only 2.61 goals per game.

Pittsburgh Penguins forward Evgeni Malkin (upper body) was placed on Injured Reserve ahead of Tuesday's tilt against the Anaheim Ducks. He departed the lineup on Sunday against the Dallas Stars and will miss at least a couple more games after Tuesday night. Pittsburgh also placed Blake Lizotte (upper body) on Injured Reserve on Tuesday. The Penguins are once again struggling with injuries in the attacking department, giving Thomas Novak a top-line role. Novak has been a regular on the score sheet recently and could cause plenty of trouble for the opposition as Sidney Crosby's partner in crime.

St. Louis Blues forward Jordan Kyrou (lower body) will miss a second consecutive game on Tuesday against the Boston Bruins and is considered week-to-week. Blues head coach Jim Montgomery told reporters that Kyrou is anticipated to miss at least one week of action, meaning he will probably sit out three more games after Tuesday night. Mathieu Joseph will get a look on the second against Boston after he recorded one assist in Sunday's 4-3 win over the Montreal Canadiens. Joseph hasn't managed points in back-to-back games since February, recording eight points (two goals, six assists) in 24 outings this season.
