Third baseman Chase Headley suffered a strained right calf during infield drills Saturday and will likely miss at least two weeks. Headley sustained the injury during a rundown drill as he was about to receive the ball. He was later on crutches in the clubhouse to protect the calf. Headley received ice treatment on Saturday afternoon and will likely have an MRI sometime Monday once swelling in the calf has subsided. The team's medical staff will know more once they receive the results of the test. At the very least, Headley doesn't seem too concerned. Frustrated? Yes, but not overly worried about the injury. "We'll probably know a little more in the next couple of days, but off the top of my head, it's probably going to be a couple of weeks," Headley said. "But it's not something I see being a huge issue, but it's going to take a little time." Headley had offseason arthroscopic surgery on his left knee and has previously had a strain of his left calf, but never the right. Last spring, Headley fractured the tip of his left thumb sliding in a Cactus League game and missed the first 14 games of the regular season. But, if anything, he has time on his side, as the Padres don't start playing games until Thursday, with Opening Day (March 30) still a long ways off. "I'd rather have it happen now than in three weeks," Headley said. "It's frustrating. You come to camp, you feel good, you put in the work in the offseason, come in great shape and you strain a muscle. But if there's a time for it to happen, I'd rather have it happen now." San Diego manager Bud Black sounded confident that this injury isn't terribly serious. "It's the nature of the game, these type of things pop up over the normal course of spring," Black said. "But the silver lining is it happened on the fourth day of our spring. He'll be fine in time." Timetables on these types of injury vary greatly.
