Tulowitzki (calf) has been given a few days off from his rehab, Coley Harvey of ESPN.com reports.
Tulowitzki seemed to be nearing a rehab assignment, but his progress has apparently stalled. Manager Aaron Boone told reporters the Yankees have sent the shortstop home for a few days to rest his lingering calf issue. Tulowitzki appeared in just five games this season before going down with injury, and this latest development indicates he's still a ways off from a return to the field.
