Harrison (forearm) said that he expects to make a rehab start Thursday with High-A Wisconsin before returning from the 15-day injured list the following week, Curt Hogg of the Milwaukee Journal Sentinel reports.
Harrison said he's targeting a workload of 5-6 innings in the rehab start, so he shouldn't require any additional buildup time if he's able to meet that goal. The 24-year-old southpaw hit the shelf July 11 due to left forearm tightness, but a precautionary MRI revealed nothing concerning, and he was cleared to resume throwing shortly afterward. Before going down with the injury, Harrison had an 8-2 record with a 3.01 ERA, 1.08 WHIP and 101:20 K:BB over 83.2 innings.
