NEW YORK -- A second opinion on Seth Lugo's elbow revealed a partially torn ulnar collateral ligament, according to a source. Lugo received a platelet-rich plasma injection and will not require surgery, but he will rest for three to six weeks.
The Mets have not confirmed Lugo's diagnosis.
Lugo, 27, did not make the Mets' Opening Day roster because of discomfort in his elbow. An MRI taken Saturday revealed only inflammation, but the Mets sent Lugo for a second opinion Tuesday in Manhattan.
