Aybar was injured in the fifth inning of Los Angeles’ 12-2 victory over the Detroit Tigers after running down the first-base line.
Aybar was replaced by Taylor Featherston in the top of the sixth inning.
Scioscia said that Aybar is expected to miss Friday’s game against Detroit. “We will definitely make sure that he's 100 percent before he gets back in our lineup. We can't stress how important he is to our club," Scioscia said to MLB.com. “So we have to err on the side of caution with him."
Aybar, 31, is the only Angels player to start every game at the same position this season. The leadoff hitter is batting .273 with a .318 on-base percentage, one home run and 15 RBI this season for Los Angeles (24-24), which is six games behind the Houston Astros in the American League West.
