BALTIMORE -- Athletics shortstop Jacob Wilson left Sunday's 2-1 loss to the Orioles in the bottom of the fifth inning with a sprained left shoulder.
Wilson went diving after Gunnar Henderson's ground ball up the middle, and after he was checked out briefly, Wilson walked off the field and was replaced by Darell Hernaiz.
Manager Mark Kotsay said Wilson will undergo imaging on Monday and there's "no timetable" for his return.
An All-Star last year, Wilson is batting .292 with three home runs and 19 RBIs this season.
