American cycling star Davis Phinney is recovering from two brain operations that were done this month in an effort to relieve some Parkinson's disease symptoms.

The 48-year-old cyclist competed in the Olympics and in 1986 became the first American to win a road stage of the Tour de France. He was diagnosed with Parkinson's eight years ago.

"He's doing good right now," said son Taylor Phinney, a cyclist who is expected to ride at the Beijing Games and was part of an Olympic gathering Monday. "They have yet to turn the machine on. They have to let the brain heal."

Barring complications, a pacemaker embedded into Phinney's brain last week will be turned on April 25. The device will send electrical signals to essentially trick the mind into ignoring certain effects of Parkinson's. If successful, there could be immediate relief.
