Athletics manager Mark Kotsay said Wednesday he doesn't expect Laureano (hamstring) to return before the end of the regular season, the Associated Press reports.

Laureano's stint on the injured list began Sunday, which would leave him just enough time to return for a handful of games in before the conclusion of the campaign. However, Kotsay threw cold water on that notion Wednesday, remarking "I'm kind of sure it's going to be a season-ending (injury)," with respect to Laureano's hamstring strain. The A's skipper did confirm the 28-year-old would begin a rehab program in coming days with the goal of being able to have a normal offseason.
