At least both Andy McDonald and Alex Steen aren't on the injured reserve... just one is. From the official Blues press release:
ST. LOUIS – St. Louis Blues Executive Vice President and General Manager Doug Armstrong announced the club has placed forward Andy McDonald on Injured Reserve today. McDonald is listed as week-to-week after suffering a left knee injury during practice yesterday at St. Louis Mills. In addition, the Blues have listed forward Alex Steen as day-to-day with an upper body injury. Steen was also injured during yesterday’s practice.
McDonald, 35, has appeared in all 18 of the Blues’ games this season tallying 11 points including three goals and eight assists. Overall, the 5’10, 175-pound forward has dressed in 666 National Hockey League (NHL) games accumulating 479 points including 178 goals and 301 assists.
Steen, 28, has appeared in all 18 of the Blues’ games this season and leads the team with 16 points including four goals and 12 assists. Overall, the 6’0, 212-pound forward has dressed in 515 NHL games totaling 292 points including 119 goals and 173 assists. The Winnipeg, Manitoba native was originally drafted by Toronto in the first round, 24th overall, of the 2002 Entry Draft.
This is not good news, as we all know. The Chicago Blackhawks are in town tomorrow night, and if the Blues want to be the team to beat that streak, it's going to be hard without McDonald, Steen, and their linemate Vladimir Tarasenko. Tarasenko is also on the IR due to concussion-like symptoms, and it is unsure when he will return.
The Blues have called up Andrew Murray from the Peoria Rivermen to fill in for McDonald for the time being. Murray has 19 points in 38 games. He also has 220 games of NHL experience between the Blue Jackets and the San Jose Sharks, so it's not like he's a fresh-faced rookie.
