Joe Nathan is seeking second opinions on his injured ligament:

The results of his latest MRI — which revealed a significant tear of his ulnar collateral ligament — have been sent to orthopedist Dr. James Andrews for another opinion. Nathan didn’t stop there, sending a copy of the MRI to Mets medical director Dr. David Altchek.

I take it Nathan sent it to the Mets doctor so he knows what not to do.
