Junk left Saturday's game against the Blue Jays in the sixth inning due to right forearm discomfort, Daniel Alvarez-Montes of ElExtraBase.com reports.
Junk didn't have the chance to finish the sixth inning, ending his start having allowed three runs on six hits and one walk across 5.2 innings while recording three strikeouts. Junk's departure came after 92 pitches. Expect the 29-year-old to undergo further evaluations throughout the next 24 hours or so. His next start is tentatively scheduled for Thursday against the Mets.
