UPDATE:

Following last weekend’s Southern 500 Greg Biffle complained that it felt as if he’d broken his ribs from the violent shaking that occurred in the Grainger Ford, after the flywheel exploded. However, according to Roush Racing sources Biffle is just fine and will be ready to go for this weekend’s Richmond International Raceway events. Roush officials said that the report of broken ribs was taken out of context [oops], somewhat, due to the beating that Biffle received in the last 50 laps of the event from the severe vibrations from the broken driveline.( Ford Racing )(9-4-2003)
