T.J. Sanders (Bills) Out Sunday vs. Chargers After Appendectomy

T.J. Sanders underwent surgery for appendicitis and is confirmed out for Buffalo's Week 4 game against the Chargers. The surgery is confirmed, and the procedure — an appendectomy — is the standard treatment for appendicitis, so there is no procedure-type uncertainty here the way there would be with, say, an undisclosed knee surgery.

Appendicitis and appendectomy fall under the SYSTEMIC flag in our classification framework. This is an abdominal/organ event, not a musculoskeletal injury, and return-to-play is governed by post-surgical healing and full-contact clearance protocols rather than tissue-specific athletic timelines. Surgery is confirmed as having occurred on or around September 22, 2026, per the resolved injury date in our tracking thread — Sanders is now approximately 4 days post-op.

For a laparoscopic appendectomy (the overwhelmingly most common approach in a healthy young athlete), the general return-to-full-contact-sport window runs roughly 2–4 weeks from surgery, contingent on resolution of post-operative symptoms, abdominal wall integrity, and physician clearance for contact. An open appendectomy, if required due to rupture or complication, extends that window meaningfully — typically 4–8 weeks or more. The source does not disclose whether the appendix had ruptured or whether the approach was laparoscopic or open, which is the primary driver of variance here. No reliable sport-specific RTP literature exists for this event type, so we anchor to post-surgical biology and standard general surgery protocols.

The team designation is Out for this week, which is consistent with any post-appendectomy timeline. There is no clinical basis to project further in-season availability without knowing the surgical findings and post-operative course. Watch for a practice return designation in the coming week as the clearest signal of his recovery trajectory.
