Dunning (undisclosed) was placed on the COVID-19 injured list Wednesday, Chris Halicke of SI.com reports.
While the Rangers haven't announced whether Dunning has tested positive for the virus, he won't be able to make his scheduled turn through the rotation Wednesday. Left-hander Jake Latz's contract was selected from Triple-A Round Rock in advance of him serving as Wednesday's starter, and it's not yet clear when Dunning will be able to return.
