Overview

• Four former 49ers — safety Talanoa Hufanga, linebacker Dre Greenlaw, tackle Mike McGlinchey and nose tackle D. J. Jones — faced their old teammates in Denver’s joint session at Levi’s Stadium.
• Hufanga playfully exchanged fake punches with Trent Williams and is expected to suit up for Denver’s preseason opener Saturday.
• Greenlaw remained sidelined with a quad strain and coach Sean Payton said he probably won’t play in the opener.
• 49ers rookie defensive end Mykel Williams left the practice early after hyperextending his knee and did not return.
• Coaches Sean Payton and Kyle Shanahan praised the clean, professional atmosphere as a valuable tune-up for both teams.
