Fire scouting report

Philadelphia Union at Chicago Fire

When: 8 p.m. at Toyota Park

TV: Channel 50

Scouting the Union: The Union (8-5-7, 31 points) comes to Chicago without leading scorer Carlos Ruiz. The club has allowed just 18 goals in 20 matches.

Scouting the Fire: Midfielder Sebastian Grazzini should see his first MLS action for the Fire (2-6-12, 18 points), but Pavel Pardo might not. A formation change could be in the works also. Defender Yamith Cuesta is suspended due to a red card. The Fire desperately needs a victory.

Next: at Portland Timbers, 6 p.m. Sunday
