Every year there are costly injuries that can really a series turn around, and this year will be no exception. There have already been injuries that might cost some teams a chance at the Cup.
Look at Daniel Sedin, who is out with a concussion after he took an elbow from Chicago Blackhawks defenseman Duncan Keith. Speaking of Chicago, Captain Johnny Toews missed his 17th straight game Tuesday night. He is planning to return soon, but head injuries are often reoccurring.
The Penguins share this same fate. I mentioned a chance of Sidney Crosby having some recurring symptoms, but another impact player is Kris Letang, who has missed time this season with concussion-like symptoms as well.
Detroit has also had their fair share of injuries this year and could easily lose a few players come playoff time. At one time or another, the Wings have played without Nicklas Lidstrom, Jonathan Ericsson, Darren Helm, Johan Franzen, Patrick Eaves and goaltender Jimmy Howard due to injury.
One last thing to watch is how important the injury to Tuukka Rask will affect the Boston Bruins. If Tim Thomas struggles, all the pressure will be on Marty Turco, who has been atrocious ever since he signed midseason.
Prediction: I think the injury to Tuukka Rask is really going to hurt the Bruins. Thomas has gotten a lot of playing time with the bleak play of Marty Turco, and he'll have to stay healthy and play well in every game for the Bruins to have a chance. That's a lot of work for a guy who turns 38 on April 17th. I think they make a serious run, but asking them to repeat may be too much.
