Both teams will be hungry for three points, with Chicago having drawn six straight matches and RSL on a 1-0-3 stretch.
Real Salt Lake and the Chicago Fire, it's safe to say, won't be satisfied by a draw Saturday.
While 3-0-5 RSL has drawn three of its past four — including a disappointing 2-2 result against Vancouver last weekend — the Fire have tied a remarkable six straight games since a season-opening loss to Chivas USA going into Saturday's match at Toyota Park (8:30 p.m., MLS Live).
Chicago will be without the services of Quincy Amarikwa (a career-high four goals this season) as the striker serves a red card suspension. His absence likely means a return to the lineup for designated player Juan Luis Anangono. Dilly Duka (hamstring) is questionable, while left back Gonzalo Segares (ankle) and midfielder Alex (hamstring) should be available.
For Salt Lake, striker Robbie Findley (patella) is nearing his return from offseason surgery, and midfielder Luis Gil (hamstring) also should be available after three games on the sidelines.
The clubs played to a 1-1 draw last May in their only meeting of 2013.
