This analysis covers the immediate impact of the Killian O'Connor injury on the USC offensive line depth chart. We break down what this means for the coaching staff as they scramble to fill a critical position before the season begins. Whether you are a dedicated fan or following college football recruitment and roster updates, this breakdown provides a clear picture of the current situation.

Big Ten football news: USC football just lost projected starting center Killian O’Connor for the 2026 season. Lincoln Riley, Tobias Raymond and the Trojans’ offensive line now face their first major test of whether USC finally has real Big Ten depth.

USC has spent the last several years trying to become bigger, deeper, more physical and less fragile under Lincoln Riley. Now the Trojans have an immediate opportunity to prove that transformation is real.

Killian O’Connor’s season-ending injury is unquestionably a major loss for USC football. But Tobias Raymond received significant work at center during the offseason, and USC may finally have enough offensive-line depth to absorb an injury without completely reshuffling the unit.

We break down what the injury means for USC’s offensive line, why Raymond becomes so important, how the rest of the projected starting five could remain intact, and why games against Oregon, Ohio State, Penn State, Wisconsin and the rest of the Big Ten will ultimately determine whether USC has truly fixed its problems in the trenches.

Most importantly, this is an early test of Lincoln Riley’s program. Championship contenders don't stay perfectly healthy. They survive when important players go down.

Has USC finally built a roster capable of doing that?
