|DID YOU KNOW?|
- The Rapids only need a draw to win their first Rocky Mountain Cup since 2006.
- Colorado continues to be one of the most surprising teams in MLS, sitting second in the Western Conference despite a rash of early-season injuries. The club's success has come without any go-to scorer, with a pair of players scoring four goals (Dillon Powers, Nathan Sturgis), and a pair scoring five (Deshorn Brown, Atiba Harris)
- After losing a bulk of its roster to Gold Cup, Real Salt Lake finally gets it key players -- Nick Rimando, Kyle Beckerman and Tony Beltran -- back, which should bode well for the Supporters' Shield front runner. Beltran, though, is suspended for the match.
- RSL's Javier Morales is fourth in assists in MLS with seven.
- RSL midfielder Yordany Alvarez was suspended three games by the league for his challenge on New York Red Bulls DP Tim Cahill, who suffered a PCL tear on the play and will be out for up to four weeks.
- The Rapids hold a slight edge in the all-time series against RSL with a 10-9 edge in the wins column.
- Both teams won their first MLS Cups in back-to-back years, with RSL winning in 2009 and the Rapids winning in 2010.
