49ers-Titans joint practice roundup: Brock Purdy continues to shine

Key Points:

• The San Francisco 49ers and Tennessee Titans held a joint practice marked by at least eight early scuffles, but the 49ers' defense, particularly their pass rush, gained momentum as practice progressed despite missing star Nick Bosa.
• The Titans lost their top two left tackles early due to ejections, which contributed to the 49ers' success in pressuring Titans quarterbacks, while the 49ers' secondary showed strength with multiple interceptions and pass breakups.
• Rookie linebacker Jaden Dugger impressed with his versatility and athleticism, earning reps with the starters and praise from Fred Warner, signaling potential for a significant defensive role this season.
• Quarterback Brock Purdy demonstrated strong performance with minimal incomplete passes, and wide receiver DeMarcus Robinson received high praise from Purdy for his route running and red zone ability, suggesting a promising offensive dynamic.
• The 49ers may rely more on tight end Jake Tonges, who showed receiving ability and versatility similar to Kyle Juszczyk, potentially becoming a key offensive contributor amid uncertainties on the offensive line and wide receiver separation.
