Megill (back) is scheduled to throw a live batting practice session Monday, Sophia Minnaert of Bally Sports Wisconsin reports.

According to Adam McCalvy of MLB.com, Megill will head out on a rehab assignment if all goes well during Monday's throwing session. The right-hander was placed on the 15-day injured list July 29 due to a lower-back strain and likely won't need more than one or two tune-up outings in the minors before rejoining the Milwaukee bullpen. Megill leads the Brewers with 20 saves on the season, but he'll likely have to settle for setup work moving forward after closer Devin Williams returned July 28 from a season-long stay on the IL.
