Giants third baseman Casey McGehee is not in the lineup for Sunday's game against the Padres and has been diagnosed with a bone bruise on his left knee, CSN Bay Area reports.
McGehee came out of Saturday's game with a left knee strain, so his absence Sunday afternoon doesn't come as a surprise. He indicated that he initially suffered the injury Monday and felt it intermittently all week, and he'll continue to get treatment for a few days.
Infielder Matt Duffy, who has seen starts at second base and third base already this season, will start at third base.
The Giants are underdogs (+120) against the Padres Sunday.
