There was good news and bad news on the injury front at Blackhawks practice Friday. Let's start with the good: Defenseman James Wisniewski only suffered a sprained knee Wednesday against Nashville and will be re-evaluated in 2-4 weeks.

Defenseman Brent Sopel hoped to be able to play Sunday despite the broken finger he suffered against the Predators but now figures to be out of the lineup for 1-2 weeks.

Brent Seabrook and Duncan Keith will log a lot of minutes on the blue line with Wisniewski and Sopel out. Dustin Byfuglien with Cam Barker and Andrei Zyuzin with recently-recalled Magnus Johansson will round out the defensive corps, though a call-up from Rockford prior to the matchup with the Kings hasn't been ruled out.

Barring any call-ups at forward, Sunday's lineup should look like this:

Sharp-Toews-Kane
Kontiola-Lang-Ruutu
Bourque-Dowell-Burish (The "Badger" line)
Koci/Samsonov-Perreault-Lapointe

Dowell (broken foot) will definitely play Sunday after resuming practice this week.

RW Martin Havlat skated before practice with Jason Williams. Both are out with groin injuries may be back within two weeks.
