St. Louis, MO (SportsNetwork.com) - The St. Louis Blues will have to make do without a pair of key forwards in Thursday's game against the Anaheim Ducks and for the near future.

David Backes and T.J. Oshie will be out of the lineup indefinitely due to concussion diagnoses, said Blues head coach Ken Hitchcock.

Backes has totaled two goals and three assists in eight games, while Oshie has been limited to one assist in eight appearances thus far.

In addition, Hitchcock said that forward Joakim Lindstrom will not play due to a flare-up of a bacterial illness which several members of the Wild and Blues have had to fend off since visiting Anaheim and Los Angeles earlier in the month.
