Priester (wrist) will begin a rehab assignment at Triple-A Nashville on Wednesday, Adam McCalvy of MLB.com reports.
Priester has been on the shelf all season while recovering from symptoms of thoracic outlet syndrome in his right wrist, but he's made enough progress with his throwing program to advance to final stage of the rehab process. According to Sophia Minnaert of Brewers.tv, manager Pat Murphy said that Priester is scheduled to cover three innings or 45-to-50 pitches Wednesday and will require at least two starts in the minors before returning from the 15-day injured list, potentially in early May. As the Milwaukee rotation currently stands now, Brandon Sproat (6.88 ERA, 1.71 WHIP in 17 innings) would likely be most at risk of losing his spot once Priester is activated.
