Lowrie missed two games earlier this week with the injury, but he has played through the pain in the Red Sox's previous three games. The results have not been encouraging, as the 27-year-old is just 1-for-14 over those three games and has committed two errors.
Manager Terry Francona hopes a few days of rest can get Lowrie over the hump as he continues to recover.
"He's still a little sore. We've got a day off tomorrow, so I think we can take advantage of it," Francona said. "What I want him to do is be able to go out and feel good. Maybe two or three days will kind of jump-start that a little bit."
Marco Scutaro, meanwhile, is providing the Red Sox with a more than serviceable replacement on the infield, as the 35-year-old veteran has been heating up this month.
Scutaro missed a full month from May 7 to June 7 with a left oblique injury, but he is hitting .400 (8-for-20) with two doubles since coming off the 15-day disabled list at the beginning of the team's current road trip.
He earned his second straight start at shortstop Sunday after swatting four singles in the Red Sox's 16-4 win over the Blue Jays on Saturday.
Scutaro's hot play in June has raised his batting average 38 points to .275 after the Venezuelan began the season in a slump, batting just .197 (12-for-61) through his first 20 games.
"You know how hitting is -- it's tough. Sometimes you just lose the feeling and it takes a while to get it back," Scutaro said. "My timing has gotten a little better. Earlier [in the season], I just lost it. That's pretty much the difference."
