Weaver exited Sunday's game against the Mariners with shoulder tightness, Mike DiGiovanna of the LA Times reports.

EDGE Analysis

Weaver threw 5.0 strong innings, allowing just one run on four hits while striking out three. At this point, it's unclear whether the shoulder ailment puts Weaver's next start in jeopardy, but at this point he should be considered day-to-day. Fernando Salas earned the win for the Angles, improving his record to 5-2 on the season.
