Despite loose bodies and inflammation in his right elbow, Jason Marquis will not need surgery.
The right-hander received a second opinion today from Cincinnati orthopedist Tim Kremchek, who confirmed the same diagnosis made yesterday by Nationals team doctor Wiemi Douoguih.
Marquis, who was placed on the 15-day disabled list yesterday, received a cortisone shot. He will not be allowed to throw for seven-to-10 days.
Doctors anticipate he'll return in six weeks.
