Rangers manager Skip Schumaker said Saturday that Jansen (forearm) is dealing with setbacks that put his return in doubt, Evan Grant of the Dallas Morning News reports.
Jansen, who was placed on the 10-day injured list in early June, has twice attempted to resume a throwing program but lingering pain has put a pause on his rehab. With Jansen out of action, Texas is relying on a combination of Kyle Higashioka and Elias Diaz behind the plate.
