Sharks coach Todd McLellan said Torres will be a game-time decision against Toronto.
Torres played his fifth game of the season Saturday against the Montreal Canadiens after being sidelined by right knee surgery until after the NHL break for the 2014 Sochi Olympics. He wasn't on the ice Tuesday for an optional morning skate and didn't practice Monday.
"He's a little bit sore and it may be a night where he has to take off just to recuperate a little bit," McLellan said. "It's taxing on that body and on his legs. We may look at doing that tonight."
McLellan was asked if Torres' soreness was related to his knee surgery or just to playing hockey after a long layoff.
"A little bit of everything," he said.
