Overview

• Bosa injured his right knee on a first‑quarter third‑down rush, went to the blue tent for evaluation, then headed to the locker room.
• He was ruled out at halftime; initial sideline tests did not indicate an ACL tear, coach Kyle Shanahan said, with further imaging planned.
• The star pass rusher was seen giving a thumbs‑down toward the stands and had two tackles before exiting.
• Rookie Mykel Williams briefly left with a wrist injury and returned as young defenders helped seal a 16-15 win on Eddy Piñeiro’s walk-off field goal.
• With George Kittle on IR and Brock Purdy and Jauan Jennings sidelined, San Francisco will monitor Bosa’s knee as Week 4 against Jacksonville approaches.
