The 24-year-old had an abscess removed from his left knee on Wednesday, and he could miss "at least 2-3 weeks," according to Todd Zolecki of MLB.com.
Writes Zolecki, "As a precaution the Phillies plan to disinfect their entire clubhouse facility following Friday's Grapefruit League game against the Red Sox at Bright House Field."
The Tampa Bay Bucs had MRSA, which tends to surface in locker room environments, going around their team last season.
Galvis, a career .230 hitter, cut his left knee earlier this month, and the infection was detected when the abscess was removed. He is being treated with antibiotics, both orally and through an IV, according to Phillies general manager Ruben Amaro Jr., but MRSA can be resistant to antibiotics.
"We've just got to take care of it," Amaro said. "It's unfortunate. He got a cut or an abrasion, and it ended up becoming an infection. That's the dangers of having a lot of people in the clubhouse at the same time. It just happens. Clearly, his timeframe would be much longer if it's MRSA. But right now, we're more concerned about his overall health than anything else. We'll see how it goes."SI WIRE: Stephen Strasburg named Nationals Opening Day starter
