Hendricks was removed from his start in Saturday's game against the Angels due to lower-back tightness, Taylor McGregor of Marquee Sports Network reports.
Hendricks lasted just two innings Saturday, allowing two runs on four hits and two walks while striking out one. The 34-year-old right-hander was on the injured list earlier in the season due to lower-back strain, so it's not the most encouraging sign that he's seemingly dealing with a related injury.
