DETROIT -- Detroit Red Wings defenseman Niklas Kronwall was hoping to play his second preseason game tonight but has been scratched due to a slight groin injury, coach Jeff Blashill said.

The Red Wings (2-4-1) wrap up the exhibition season against the Toronto Maple Leafs at Ricoh Coliseum (7 p.m., NHL Network).

Kronwall, who made his preseason debut Thursday after recovering from back spasms, is listed as day-to-day.

"I'll know way more Tuesday," Blashill said. "At the end of the day he's going to have to practice Tuesday in order to be ready Thursday (for the season opener vs. Minnesota), in my mind. So if he's not practicing Tuesday you will have your answer."

Defenseman Nick Jensen (thumb) practiced today.

"I expect him to be ready (for Thursday)," Blashill said. "We're being very precautionary right now, but I can't guarantee it."

Here are the Red Wings' lines tonight:

Justin Abdelkader-Michael Rasmussen-PA Parenteau

Dylan Sadowy-Luke Glendening-Luke Witkowski

Matt Lorito-Axel Holmstrom-Dominik Shine

Matthew Ford-Dominic Turgeon-Colin Campbell

On defense:

Brian Lashoff-Vili Saarijarvi

Dan Renouf-Joe Hicketts

Xavier Ouellet-Dylan McIlrath

In goal:

Petr Mrazek (starting)

The Red Wings put goaltender Tom McCollum on waivers today. If he clears by noon Sunday he will be assigned to the Grand Rapids Griffins.
