Birdsong (forearm/elbow) is scheduled to undergo Tommy John surgery next week, Alex Pavlovic of NBC Sports Bay Area reports.
An MRI on Birdsong's right arm Sunday revealed a Grade 2 forearm strain and a UCL sprain. After receiving a second opinion, the 24-year-old righty has opted to undergo surgery to address the issue, which will rule him out for the entire 2026 campaign in addition to the start of 2027.
