The San Jose Sharks have struggled to score for most of the season and may be without their most productive player until after Christmas.
Logan Couture is not expected to be in the lineup Thursday night when the Sharks face the sliding Vancouver Canucks in the opener of a three-game homestand.
Couture suffered a concussion after being hit by Alexander Burmistrov in Thursday's 4-3 overtime loss to Vancouver and did not suit up in Monday's 5-3 setback to the Edmonton Oilers in the finale of a three-game Western Canada swing.
