Overview
- Day left his opening round after 10 holes when he was seven-over and was carted off the course with his caddie, a withdrawal the PGA Tour confirmed.
- Thursday’s exit continued a long pattern of spine troubles that have prompted roughly 12 injury withdrawals in his career and interrupted major events.
- Past treatments cited in coverage include a 2019 MRI showing an L4‑L5 annular tear, cortisone injections, and a 2020 rhizotomy, all linked to recurring back pain.
- The PGA Tour has not provided a detailed medical update, so his participation in the Travelers Championship next week is currently uncertain.
- For Day, a former world No. 1 and 2015 major champion, these recurring back problems have already required swing changes and time away from competition and could force another short break that affects his form and schedule.
