Tim Howard made two saves on his Colorado debut as the Rapids played to a 0-0 draw with the Portland Timbers on Monday night.
Howard dove to his right to stop Darren Mattocks' right-footed shot in the 54th minute and denied Lucas Melano with his foot 10 minutes later.
Portland goalkeeper Jake Gleeson had four saves for his second shutout of the season.
Howard, who played for the MetroStars (now the New York Red Bulls) between 1998 and 2003, returned to MLS after 13 years in the Premier League with Manchester United and Everton.
