Korpikoski (head) was placed on injured reserve Tuesday.

Analysis:

The 29-year-old winger had been playing on the bottom lines for the Oilers, but it appears he is going to need more time to recover from the head injury he sustained on October 27 in a game against the Wild. It is unclear at this time how long he will be out for.
