Jered Weaver leaves game with lower back tightness
JUL 07, 2014 10:42p ET
Weaver, 9-6 with a 3.56 ERA, has had an injury-free season, although he has had back issues in the past.
He worked two perfect innings against the Blue Jays, then went to the mound for the third inning and threw several warm-up pitches before leaving.
Right-hander Matt Shoemaker, who was scheduled to pitch Thursday when the Angels open a four-game series at Texas, replaced Weaver. Now, manager Mike Scioscia will have to reshuffle his rotation, making it likely that struggling lefty Hector Santiago will get another start.
