Mize was removed from Saturday's game against the Twins in the third inning due to a right ankle sprain.
The velocity on Mize's pitches steadily decreased as Saturday's game went on, prompting his removal during the third. His next start is lined up for next weekend on the road against the Rays, but whether he's cleared to pitch will be determined by additional tests and how his ankle responds to treatment over the next few days. Mize was acquired by the Padres from the Tigers at the Aug. 3 trade deadline.
