Weathers was optioned to Triple-A El Paso on Thursday.
Weathers was hit hard Wednesday in a spot start, as he allowed five earned runs on five hits and three walks against the Dodgers. The move will likely end his first regular season at the major-league level, and he posted a 5.32 ERA and 1.38 WHIP with a 72:30 K:BB across 94.2 frames.
