Athletics' Scott Alexander: Dealing with stress reaction

Alexander is dealing with a stress reaction in his left rib and will be sidelined for an undetermined period of time, MLB.com reports.

The veteran southpaw struggled across three Cactus League appearances, allowing eight earned runs on nine hits and a walk over 2.1 innings. Alexander's injury could sideline him into the early portion of the season, although more clarity on his potential return timetable could be gleaned in coming days.
