Kris Draper's injured groin is going to keep him out for at least another week, because the Red Wings have put him on injured reserve.
Taking Draper's spot on the roster for now is Doug Janik, who will play tonight against the Colorado Avalanche.
By being placed on injured reserve, Draper is ineligible to play "for a period of not less than seven days." He will still be able to attend meetings and travel with the Red Wings and even practice. Because the Wings didn't expect him to be ready to go for an actual game for at least the next week, though, they opted to put him on IR and fill his spot on the roster with Janik.
