Ramirez's X-ray on his knee revealed no signs of a fracture, Jeff Passan of ESPN.com reports.
Ramirez fouled a ball off his knee Sunday against the White Sox and had to be carted off the field. He appears to have escaped serious injury, though his return timetable remains unclear. If he misses time to start the year, Max Moroff, Brad Miller and Eric Stamets would all be likely to start somewhere in the infield, with Jason Kipnis and Francisco Lindor each heading to the injured list with calf strains.
