A magnetic resonance imaging performed after Carpenter’s abortive August start found no structural damage in either Carpenter’s surgically repaired shoulder or elbow.

At times, the 2005 NL Cy Young Award winner has been unable to fully extend all the fingers on his pitching hand.
Neurologists have concentrated their focus on the brachial plexus, a bundle or "superhighway" of nerves running from the spine to the neck and beneath the collarbone. The brachial plexus is responsible for firing most of the muscles in the upper arm.
