Craig Anderson limped into Scotiabank Place with Senators GM Bryan Murray Friday morning.

That was the only good sign for the Senators.

Ottawa's top goaltender wasn't on the ice when the pucks were flying at noon and he certainly won't be in the net to face the visiting Toronto Maple Leafs in the Battle of Ontario Saturday.

Just how long Anderson, the NHL's top goalie this season, is going to be out with a sprained ankle isn't known, but GM Bryan Murray and coach Paul MacLean both told reporters they don't expect the 31-year-old to be out long-term.

Bowled over by New York Rangers winger Chris Kreider after tripping on defenceman Marc Methot's stick in Ottawa's 3-2 shootout win Thursday night, Anderson won't be able to return until he is comfortable enough to resume skating.

League sources say these injuries are usually two-to-four weeks, but the Senators are hopeful that won't be the case.

"(The doctors) have told us it's day-to-day -- that it's not a two-to-three-week type of thing," said MacLean. "It's more of minor (sprain) is what they said."
