Weaver has inflammation in the left hip, the team said, and will have an MRI and other medical tests on Monday to determine the extent of the injury.
Weaver, 32, has been pitching through the injury “for the last couple of starts,” manager Mike Scioscia told reporters, according to The Los Angles Times, and has a 6.58 ERA in his last four outings. He gave up four runs on six hits in 5 2/3 innings in his start Saturday against the Oakland Athletics.
Weaver's fastball is averaging 85.1 mph this season, down from 86.8 last season, according to PITCHf/x. After leading the American league in wins last season, Weaver is 4–8 with a 4.75 ERA.
Opposing hitters are batting .292 against Weaver this month, and he has just 11 strikeouts in his past 26 innings.
The Angels (35–34) are in third place in the American League West, 4.5 games behind the first-place Houston Astros.
