49ers Preseason Opener: A Snoozefest

San Francisco Falls to Titans 17-13

Takeaways from a Dull Night in Nashville

Preseason football is hardly ever exciting, but it was a particularly dull night for San Francisco 49ers coach Kyle Shanahan. The 49ers dropped their preseason opener against the Tennessee Titans 17-13 at Nissan Stadium on Saturday night.

Trey Lance, who worked in the offseason to learn new coach Brian Callahan's system, completed 4 of 5 passes for 61 yards before giving way to Nate Sudfeld in the second quarter. The 49ers' offense managed just 180 yards of total offense, while the Titans racked up 350 yards.

Here are three takeaways from the 49ers' preseason opener against the Titans:

• The 49ers' offense needs to find its rhythm.
• The 49ers' defense played well against the Titans' first-team offense.
• Rookie safety Talanoa Hufanga made a splash with a big hit in the second quarter.
