Pomeranz was removed from Sunday's intrasquad game due to a leg issue, Kevin Acee of The San Diego Union-Tribune reports.
Pomeranz was in his second inning of work when he apparently made an awkward landing after a pitch. Per Acee, the 31-year-old wanted to continue but was pulled "in an abundance of caution." Pomeranz reportedly walked off the field without apparent discomfort, so there is reason to be optimistic that he is not dealing with a serious injury.
