"The flexor muscle basically protects your ligament. That's one of the things they're looking at, to see how that ligament looks. Obviously I think you could probably go through this clubhouse and look at everybody's ligament and it's not going to be like a 12-year-old's ligament. So that's one thing they'll look at, to see if that ligament has been compromised."
There isn't much Hanrahan can do from a rehab standpoint until the team gets the evaluations from those two doctors.
"Joel is still in a shutdown period," said manager John Farrell.
Things appear to be headed in a better direction for Andrew Bailey, who is on the disabled list with a right biceps strain.
"With Andrew, we're hopeful to put a ball in his hand tomorrow to get his arm moving, to get him through the range of motion and initiate a throwing program," said Farrell.
Bailey is eligible to come off the disabled list Tuesday when the Sox begin a road trip in St. Petersburg. The club hasn't discussed yet whether he would pitch in a Minors rehab game or two before being activated.
