Lowrie, who has spent most of this season on the disabled list with a sprain of the same wrist, had surgery in April to repair a related ligament. He said earlier this weekend that he was unsure if the tingling sensation that forced him to leave Thursday's game against the Yankees was related to the operation.
The answers, the Red Sox hope, will surface in Phoenix, where Lowrie will visit with Dr. Donald Sheridan -- the same specialist who performed the surgery.
"If it isn't serious -- which hopefully it isn't -- then if there's some pain or some discomfort, he can play, not worrying he's going to hurt something," Francona said. "That's kind of the idea behind that."
Lowrie, 25, has played just 19 games in what was supposed to be his first full season in the Major Leagues, hitting .143 with one home run. The Sox claimed infielder Chris Woodward off waivers from the Mariners on Friday to serve as something of an insurance policy in the case of an extended absence for Lowrie.
Woodward made his Sox debut that same night, coming on as a defensive replacement in the eighth and playing the final eight innings.
Lowrie, meanwhile, watched from the bench, in what has become an increasingly frustrating season for him.
"I don't think when he came to Spring Training this is probably how he would have drawn it up," Francona said. "But how you handle frustration, that's what defines your season. It's not always easy. We know that. You want guys that will fight through it, because every so often, it is hard. This is a tough game."
After using every member of their bullpen in Friday's 15-inning affair, the Sox replaced Lowie with Gonzalez, rather than with another position player. Gonzalez, who had been starting games with the PawSox, was 7-10 with a 5.31 ERA in that role. He last pitched in the big leagues last season, making four early April relief appearances for the Padres.
"It was his day to start today in Triple-A, so it gives us some length," Francona said prior to Saturday's game. "Hopefully, we don't need it."
