Overview

• In the second quarter at SoFi Stadium, a sprinting official accidentally knocked into Lamb as he stood in street clothes near the restricted white sideline during Dallas’s preseason opener against the Rams.
• Officials flagged Lamb for unsportsmanlike conduct, nullifying a 51-yard Los Angeles gain that followed Shaun Jolly’s pass interference on Jonathan Mingo.
• The four-time Pro Bowl receiver was watching from the sideline with Dak Prescott and George Pickens sidelined, illustrating how non-playing stars remain subject to boundary rules.
• Lamb emerged uninjured and shared a laugh with teammates after the collision, underlining the unusual nature of a referee-player collision.
• With offseason coaching controversies and contract disputes still unresolved, the Cowboys are tightening sideline standards to prevent similar disruptions ahead of Week 1.
