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