MONZA, Italy (AP) _ Michael Schumacher slammed into a rubberized wall at about 185 mph during practice Tuesday, but the Formula One leader was back at his garage after a brief hospital stay.

Schumacher was one of 10 racers practicing for the German Grand Prix on July 29. His Ferrari lost control and skidded off the Monza course, hitting the protective wall.

Schumacher, bidding for a fourth driver's title, was rushed to a hospital, where he was checked for less than 30 minutes. The 32-year-old German returned to the Ferrari garage at the Monza complex without any apparent injuries.

Giancarlo Fisichella, driving his Benetton Renault behind Schumacher, told the ANSA news service that the impact with the wall was ``violent.''

There were no immediate reports on damage to the vehicle, which was the only Ferrari brought to Monza for testing Tuesday.

If Schumacher wins on his home course, he will match Alain Prost's career record of 51 victories.
