Wilson (shoulder) will begin a rehab assignment at Triple-A Las Vegas on Saturday, Jason Burke of Roundtable.io reports.
Wilson has been sidelined by a partial left shoulder dislocation since mid-May, but he's now been given the green light to begin testing his shoulder in a competitive setting. The A's haven't said exactly how many minor-league games they plan to have the 24-year-old play, but he figures to come off the injured list sometime next week.
