DETROIT -- Detroit Red Wings forwards Darren Helm and Tomas Holmstrom, both idled by groin injuries, returned to practice on Thursday, but each left about halfway through, as a precaution.

Their status for Saturday's game in Toronto (7 p.m., Fox Sports Detroit) is questionable, at best.

“I don't think so (Saturday), but there's another practice tomorrow, so we'll see what happens,'' coach Mike Babcock said. "We're set up to go without them. But they're good players, when they're available, we'll use them.''

Helm has missed three games. Holmstrom has sat out four.

"See how I feel tomorrow, that will probably be a bigger indicator,'' Helm said. “I wasn't pushing myself too hard. Couple of times I tried to get up to full speed, but never went after it too hard. Felt good, didn't feel it at all when I was skating.''

But he didn't sound optimistic for Saturday.

“If it feels unbelievable, maybe,'' Helm said. "We play back-to-back, so it's pretty tough jumping into back-to-back with this kind of injury. So maybe Saturday off and shoot for Sunday (at Chicago). But if it feels really good, then we'll see.''

The only change Babcock made to the lines was inserting Chris Conner where Joakim Andersson had played the past four games. Here are the lines they skated with:

Franzen-Datsyuk-Bertuzzi

Filppula-Zetterberg-Hudler

Miller-Abdelkader-Cleary

Nyquist-Emmerton-Conner

Lidstrom-White

Kronwall-Stuart

Ericsson-Commodore/Kindl
