Paxton was removed from Sunday's start against the Astros during the first inning due to a right leg injury, Matt Kawahara of the Houston Chronicle reports.
The left-hander allowed two hits and recorded two outs before suffering the injury, and he could barely put any weight on his right leg as he was helped off the field. The specifics of the situation are unclear, and Paxton's status should be updated by the team in the near future.
