Outlook: After a 1-1 friendly draw with Chivas Guadalajara last weekend, United resumes MLS regular season play in search of its first road victory (0-6-3 with one goal for, 12 against). With eight goals overall, United is on pace to break its own league record for scoring futility, set in 2010. The club has not scored in the run of play (just two penalty kicks) in the past eight regular season matches. However, De Rosario and MF Nick DeLeon are back in the mix after missing several weeks with injuries. Silva is almost certain to make his first regular season appearance since being acquired from Toronto FC. Porter returned from Canadian Gold Cup duty. While the attack has struggled, the defense has stabilized: five goals conceded in six games. Willis, who was sensational in a 0-0 draw at Colorado two weeks ago, is expected to make his third consecutive start in place of Bill Hamid (U.S. national team assignment). Center back Dejan Jakovic is available after missing eight league games with an adductor strain. The Fire is without starting GK Sean Johnson (U.S. team). Magee is tied for second in MLS with 11 goals — five since joining the Fire from Los Angeles on May 25.
