It was another gritty performance by the 49ers in their 19-12 win over the Dallas Cowboys in Sunday's divisional playoff game at Levi's Stadium, and Brock Purdy’s PFF grades show poise against his toughest opponent to date.
The rookie quarterback completed 19 of his 29 attempts for 214 yards and -- maybe most importantly -- committed no turnovers. Purdy might not have thrown for any touchdowns, but he did enough to set the offense up for a rushing touchdown by Christian McCaffrey and four field goals by Robbie Gould.
The offensive line had a challenging day face to face with Cowboys star edge rusher Micah Parsons, who also affected the run game significantly. Running backs McCaffrey and Elijah Mitchell helped contribute to the hard-fought 113 total rushing yards, and Purdy completed passes to five different targets.
On the defensive side, it also was a group effort. Key interceptions by Fred Warner and Deommodore Lenoir helped the 49ers advance to Sunday's NFC Championship Game against the Philadelphia Eagles at Lincoln Financial Field.
Here are highlights from the 49ers' divisional-round PFF grades:
Offense:
QB Brock Purdy - 67.7

Purdy still was effective downfield, completing six of his eight attempts for 126 yards on targeted throws of 10 or more yards downfield. The 23-year old completed two of his four attempts of 20 yards or more, with both completions coming between the hashes.
