“Obviously we're concerned about it,.” Roenicke said Tuesday.

Dr. James Andrews will review the MRI.

Sale threw about 18 pitches in batting practice Sunday, the first time he faced hitters since he gave up five runs over 6 2/3 innings in a win at Cleveland on Aug. 13. He went on the injured list with elbow inflammation, finishing 6-11 with a 4.40 ERA in 25 starts.

He already was slated to start this season on the IL after reporting to camp with pneumonia, setting him back by about two weeks.
