Tyler Bass Misses Entire 2025 Season Following Surgical Pelvic Injury

Tyler Bass (Buffalo Bills) missed the entire 2025 NFL season due to a surgically-treated pelvic injury — a significant, debilitating event that placed him firmly in the SEVERE category and warranted offseason recovery framing from the outset. The pelvis is a complex structural region anchoring the core musculature, lower extremity kinetic chain, and hip mechanics — all of which are critical to a kicker's power generation and plant-leg stability.

OTM Three-Axis Classification:

• Axis 1 — Tissue Type: SP (Spine/Trunk/Pelvis) with likely BON (pelvic ring/ramus) or MYO/LIG involvement — INFERRED from "pelvic injury" language; specific tissue not publicly confirmed
• Axis 2 — Structural Severity: Grade 3 (surgical intervention confirmed) — grade is CONFIRMED by surgical disclosure; specific structural findings are INFERRED
• Axis 3 — Anatomical Region: SP (Spine/Trunk/Pelvis)
• Flag: SURGICAL — MD review queue elevated
• Evidence Tier: T3 (Low Confidence) — pelvic injuries in NFL kickers have limited published RTP literature; biology-anchored estimate applied

Confidence note: Surgical escalation is CONFIRMED. Specific pelvic structures involved (pelvic ring, acetabulum, pubic ramus, soft tissue) are INFERRED — not publicly disclosed. The "Questionable" team timeline designation is entirely inconsistent with a season-ending surgical pelvic injury and carries no meaningful clinical signal here; it appears to be a reporting artifact or placeholder.

Team Timeline vs. OTM Estimate: A "Questionable" designation for a player who missed an entire season due to pelvic surgery has no clinical coherence. OTM applies biological and surgical RTP logic — not the team tag — for any meaningful estimate. The team's designation is disregarded as a valid clinical data point in this context.

For pelvic surgical injuries at this severity, post-surgical healing floors range from 3–6 months (soft tissue/ligamentous) to 6–12+ months (osseous/structural), with functional sport RTP for a kicker — who demands precise plant-leg mechanics and explosive hip-through motion — likely tracking toward the longer end of that window. Full offseason recovery and clearance ahead of the 2026 season is the operative clinical question now.
