San Francisco 49ers manage defensive injuries and offensive guard performance

The San Francisco 49ers are managing significant roster challenges due to injuries and positional competitions. The defensive line has been heavily impacted, with Alfred Collins lost for the season due to a patellar tendon tear. Additionally, James Thompson Jr. is sidelined with a high-ankle sprain, and C. J. West was placed on injured reserve with a knee bone chip. Rookie defensive end Romello Height is also uncertain for the upcoming Week 3 game against the Arizona Cardinals following hand surgery. Defensive coordinator Raheem Morris has emphasized a ‘next-man-up mentality,’ noting that rookie Gracen Halton has impressed coaches despite the depth issues.

On the offensive side, Connor Colby has emerged as the starting left guard following an offseason competition. Through the first two weeks against the Los Angeles Rams and Miami Dolphins, Colby has provided stable pass protection for Brock Purdy, allowing only two pressures and zero sacks across 61 opportunities. While his pass-blocking efficiency is high, analysts suggest there is room for improvement in his run-blocking consistency to better support the team's rushing attack.
