Angels' Matt Thaiss: Further tests come back negative

Thaiss underwent further testing on his injured right shoulder, which came back negative, MLB.com reports.

Thaiss was placed on the 10-day injured list last week with right shoulder inflammation and additional testing has ruled out structural damage. The catcher said he's most affected when throwing but is hopeful it will be a short-term absence. He's eligible for activation in early September, but there's no official return timetable at this point.
