Dustin Pedroia will undergo an MRI on his left ankle and knee on Monday, Red Sox manager John Farrell told reporters (including MassLive.com’s Jen McCaffrey and The Boston Globe’s Peter Abraham). After suffering the injury on a hard slide from Manny Machado on Friday, Pedroia sat out Saturday’s game and is also not in Sunday’s lineup, as Farrell said the swelling around Pedroia’s lower leg area hasn’t yet subsided. While the MRI is being performed “just to rule anything out,” according to Farrell, it’s worth noting that Pedroia underwent surgery on that same knee to remove part of his meniscus last October.
