Weber was removed from Saturday's game in the fourth inning with what appeared to be a biceps injury, Bob Dutton of The Tacoma News Tribune reports.
Prior to exiting, Weber trekked through 3.2 innings while allowing one run on three hits. The only reason Weber was starting Saturday's game was because of the multitude of injuries surrounding Seattle's pitching staff, and now he'll get added onto the list. It's unclear how severe the ailment is or whether he'll require a DL stint, but more information should be revealed once team doctors are able to examine him.
