Lowrie was placed on the disabled list before Monday's game in Oakland and flew back to Boston, where he was seen by Red Sox doctors.
"He's seen three guys already in Boston," Red Sox manager Terry Francona said. "I think [Red Sox medical director] Tom Gill feels pretty confident about him seeing this guy and Jed is on board. So we'll get another opinion tomorrow and hopefully have a little bit better information then."
The injury is of particular concern because Lowrie played most of last season with a small non-displaced fracture in that same wrist.
"It's certainly the same vicinity," Francona said. "Saying that, there's so much stuff going on in a little area there. I think what they're trying to do is make sure and trying to pin down exactly, 'OK, what is leading to what?' I can understand it's not the easiest thing to figure out. I think out of respect to Jed, we're just trying to make sure we get the best possible answers we can."
As Lowrie tries to get a handle on his situation, the club's other injured shortstop -- veteran Julio Lugo -- is ramping up his rehab.
Lugo, who underwent right knee surgery in March, will play in his first extended spring training game on Wednesday, serving as the designated hitter. He'll play Friday, Saturday and Sunday in Fort Myers, Fla., as well, playing shortstop and DH, and then report to Fenway Park on Monday.
Assuming Lugo gets a clean bill of health from the Red Sox, he could report to Triple-A Pawtucket as early as Tuesday.
Francona said it's too soon to determine when Lugo will be ready to get back in the Boston lineup.
"He ramped it up pretty good today," Francona said. "I'm sure he got a little kick in the pants, too, seeing what happened [to Lowrie]. But I think we'll get a little bit better feel when we see him on Monday."
In the meantime, Nick Green will continue to start at short for the Red Sox with Gil Velazquez serving as the backup.
