Manning (biceps/shoulder) will begin a rehab assignment at Triple-A Toledo next week, Joey Pollizze of MLB.com reports.
EDGE Analysis
Manning resumed mound work last weekend, and he threw an up-down bullpen session Friday. The right-hander will likely require several rehab appearances since he's been on the injured list for two and a half months, but it's possible that he'll be cleared to rejoin the Tigers sometime in late July or early August.
