49ers bolster run defense with Odighizuwa, returning Bosa, and rookies
Summary

The San Francisco 49ers are looking to improve their run defense in 2026 with the addition of defensive tackle Osa Odighizuwa and the return of edge rusher Nick Bosa. In 2025, the 49ers ranked 14th in stopping opponent carries for zero or fewer yards. Odighizuwa's run-stop win rate of 39% last season showcases his potential impact. Bosa's return from injury, alongside promising rookies Romello Height and Gracen Halton, sets a foundation for a stronger unit this upcoming season. Training camp will be a key period for the team’s defense.
