Fanendo Adi and Rodney Wallace will lead the line for the Portland Timbers in their MLS clash against the Chicago Fire at Providence Park.
The Timbers have elected to name an unchanged team from the side that drew 0-0 against the San Jose Earthquakes last week.
Frank Yallop's men are also unchanged from their 2-0 victory over Dallas last week as David Accam and Jason Johnson again start up front.
Shaun Maloney continues to operate on the left wing of the Fire midfield, after Hull City had a bid for his services rejected this week.
Portland Timbers: Kwarasey; Powell, Borchers, Ridgewell, Villafana; Johnson, Chara, Nagbe, Valeri; Wallace, Adi
Chicago Fire: Johnson; Palmer, Gehrig, Larentowicz, Jones; Shipp, Polster, Cocis, Maloney; Johnson, Accam
