Colorado Rapids left back Anthony Wallace will miss the rest of the 2011 season after undergoing surgery to repair cartilage in his right knee, the club announced Monday.
The damage was discovered while Wallace was rehabilitating from a left knee sprain suffered in the Rapids' Aug. 5 game against the Columbus Crew. The game was his first back since recovering from knee tendinitis, but now he will miss the Rapids' remaining four games and any potential playoff games. He finishes the season with ten appearances including eight starts and one assist to his name.
Wallace, 22, was the ninth overall pick for FC Dallas in the 2007 MLS SuperDraft, but was traded to Colorado in 2010 for a fourth round pick in the 2011 MLS SuperDraft and a conditional pick in the 2012 draft. He played in all four of the Rapids' playoff games en route to the team's 2010 MLS Cup win.
Wallace has represented the United States extensively at the youth national team level and earned his first and to date only senior cap against Chile after being called up for the national team's January training camp.
