Sheppard evidently got injured during an hour-long practice on Thursday in Chicago. San Jose might also have a lineup change coming on the back end, but Sharks coach Todd McLellan didn't specify what that might be.
"We'll look at inserting a new forward [for Sheppard],” McLellan said. "Potential change [on defense, as well]. We'll have to see after the skate how guys feel."
Scott Gomez will likely draw the assignment to replace Sheppard, while the defense situation is a little tougher to predict, not knowing which players will be re-evaluated after the skate.
Sheppard had played in seven straight games and has one assist in nine games.
