Nobody has said what, and Andrews, probably the foremost expert on elbows, will likely bring more clarity to the matter.
"I don't know about the severity of it right now," said Red Sox manager John Farrell. "We know there have been findings based on the MRI. Anytime the elbow is talked about, you go to someone who is probably the source in our industry -- and that's Dr. Andrews -- to take a further look at this."
If there is ligament damage in Vazquez's elbow, that would probably necessitate Tommy John surgery, which typically has about a nine-month recovery time for position players.
Though ligament transfer surgery hasn't necessarily been common for catchers, the Orioles' Matt Wieters had the procedure last season.
