Chicago Fire defender Matt Polster suffered a Grade 2 right MCL sprain on March 16 and is expected to miss five to six weeks, the team announced Monday.
Polster started and recorded an assist in Chicago’s MLS season opener against Sporting Kansas City but didn’t play in the club’s 2-1 loss to Minnesota United on Saturday because of the injury. Rafael Ramos started at right back in his place.
Polster, 24, appeared in 22 games (21 starts) for the Fire last season, totaling a goal and seven assists. He has three goals and 10 assists in 80 games (73 starts) across four seasons with Chicago.
