[MLS] Colorado's makeover took another tweak this week with the trade of forward Quincy Amarikwa to the Rapids from San Jose. He joins a roster a bit thin at forward, with starters Omar Cummings and Conor Casey backed up by rookie Andre Akpan and Ross Schunk, who is currently injured.

Amarikwa, a second-year forward from UC Davis, joins recent acquisitions Claudio Lopez, Marvell Wynne, Jeff Larentowicz and Wells Thompson on a Rapids roster that seems to change by the day.

Lopez might get a chance to debut for the Rapids when they play his former team, Kansas City, on Saturday; Larentowicz stepped right into the starting lineup alongside captain Pablo Mastroeni, and Wynne has started the first two matches at centerback.

Amarikwa, 22, scored one goal and registered two assists last year while playing 24 games (one start) for the Quakes in his rookie season. He played seven minutes as a substitute March 27 as the Quakes lost their opener to Real Salt Lake, 3-0. In exchange for Amarikwa, San Jose received a second-round pick in the 2012 SuperDraft.

San Jose, which didn’t have a league match last weekend, beat Santa Clara University, 4-1, in a scrimmage Tuesday night. Joey Gjertsen, Ramiro Corrales, Ryan Johnson and Arturo Alvarez scored for the Quakes, who play at Chicago Saturday in the Fire’s home opener.
