Chicago Fire rookie goalkeeper Sean Johnson will miss Friday's match when Chicago hosts the Columbus Crew.
According to the team's official site, Johnson had internal bleeding in his eye after taking a shot in the face during a scrimmage.
"After seeing the doctor, he made me aware this type of injury just takes a bit of rest," Johnson said to Chicago-Fire.com on Wednesday. "We're just taking precautions to make sure there are no complications and I have a speedy recovery. If all goes well, I should be back to training pretty soon."
Johnson, who has started in every match since SuperLiga, will be replaced by Andrew Dykstra. Dykstra was the team's opening-day goalkeeper shortly after the team waived Jon Busch.
Dykstra has made 14 starts in regular-season play this year. His last match was a 5-1 loss to Monarcas Morelia during an opening-round match in SuperLiga on July 14. Johnson started in every match since then.
Johnson has posted a 3-6-3 record, allowing 1.33 goals per game. Dykstra is 4-5-5 this season with a 1.36 goals allowed average.
The Fire (7-11-8) have four matches remaining this season. They need to win out simply to maintain their slim mathematical chance at a postseason.
The Fire can officially be eliminated from postseason contention if they lose or draw against Columbus, or if the Colorado Rapids take at least a point against FC Dallas and the San Jose Earthquakes defeat D.C. United.
