Foley was placed on the 7-day injured list by Triple-A Toledo on Thursday due a right shoulder strain, Cody Stavenhagen of The Athletic reports.
Foley struck out nine and permitted just one hit over 6.2 scoreless innings in his first five appearances with Toledo, but he hadn't pitched in several days and now it's been revealed why. It's not clear how long he might be sidelined, but the former Tigers closer will not be an option for the big club for a while.
