Walters (oblique) will undergo further tests to determine the extent of his oblique injury but could miss a considerable amount of time, MLB.com reports. "He's pretty sore," manager Terry Francona. "We're going to have to get him checked and see where that goes." The Indians were hopeful that the injury wasn't related to the right oblique injury that plagued Walters at the end of last year but a further examination Friday indicated the two may be related. Walters was an intriguing power source in AL formats as a utility infielder for the Tribe but those plans may be put on hold pending the injury diagnosis.
