Quick Takeaways

Sam Darnold was the highest-graded quarterback for either team, earning a 68.9 overall grade. Still, it was his lowest mark of the preseason. Darnold finished the game 6-of-11 for 89 yards and a touchdown.

Brandon Allen was second among the 49ers quarterbacks, earning a 59.8 overall grade. He finished just 2-of-6 for 23 yards and an interception.

Surprisingly, starter Brock Purdy was the lowest graded of any quarterback in the game, finishing with a 50.6 overall grade, his lowest of the preseason. Purdy finished the game 5-of-9 for 73 yards, adding five rushing yards and a rushing touchdown.

Linebacker Demetrius Flannigan-Fowles earned the game's highest overall grade, albeit in only 12 snaps. Pro Football Focus credited him with a pressure and a sack, while official league stats credited him with 0.5 sacks (PFF doesn't credit shared sacks). The analytics site had Demetrius Flannigan-Fowles earning two tackles and three stops. The linebacker was targeted once, allowing minus-five yards.

Some good news along the 49ers offensive line: Jaylon Moore earned his highest preseason grade at the left tackle spot. His run-blocking grade of 85.4 and pass-blocking grade of 85.9 were both team highs.

The second-highest grade along the offensive line came from Moore's opposite side, with Matt Pryor at right tackle. The 49ers offensive line did not allow a sack in the game and allowed only two pressures.

Rookie cornerback D'Shawn Jamison earned his highest overall and run-defense grades of the preseason, allowing only one reception for eight yards on two targets. He was also credited with a pass breakup.
