Moraes to have cyst removed

SAO PAULO -- Brazilian IndyCar driver Mario Moraes will undergo head surgery this week in Sao Paulo to have a cyst removed from an area near his ear canal.

Moraes says the cyst was discovered after he underwent a battery of exams in the United States ahead of Monday's race in St. Petersburg.

Moraes finished 21st in the race, which was postponed from Sunday because of rain. He was caught up in a crash with English driver Dan Wheldon, who apparently had a mechanical problem and crashed into Moraes.

The Brazilian driver said in his Twitter feed that "it was very hard to concentrate" on the race after finding out of his health problem.
