Lockridge suffered a deep laceration down to the bone of his right knee during Friday's win over the Yankees, Adam McCalvy of MLB.com reports.
X-rays on Lockridge's knee came back negative for a fracture, but manager Pat Murphy said that the outfielder is still going to be sidelined for "a while" because of his laceration. That means a trip to the injured list is probably in Lockridge's future, and a return to the majors is likely in the cards for Blake Perkins.
