Mwanga, 21, was the first overall pick of the 2010 MLS SuperDraft by the Philadelphia Union. He had a promising rookie season, scoring seven goals, but has only managed eight goals in his next two seasons. He was traded to Portland in June 2012.
“Danny is a young, exciting forward who has proven his ability to make an impact in MLS,” said Rapids technical director Paul Bravo. “He will be a good fit for our system and we’re looking forward to welcoming him into our squad.”
“Danny was with the Timbers for a short time, but we appreciate his contributions to the club. He was a great ambassador for the club and the sport in the community,” said Gavin Wilkinson, Timbers general manager. “It is a good opportunity for him in Colorado and we feel this move is beneficial for all involved. We wish him well.”
