SAN FRANCISCO -- Outside linebacker Ahmad Brooks wasn't thrilled by the way the New York Giants ran the ball against the 49ers on Sunday.
And that was before he learned that Giants running backs Ahmad Bradshaw and David Wilson amassed 151 yards in a 26-3 rout of the 49ers.
"One and a half? One fifty?" Brooks asked. "Ah, (shucks). Damn. I didn't know that they ran for that much."
Perhaps more alarming, the Giants did most of their damage in the fourth quarter, when the 49ers knew the run was coming.
The Giants totaled 61 yards on 20 carries through three quarters. Bradshaw and Wilson added 91 on 15 carries in the final quarter, with the 49ers needing to stop the run and get the ball back to their offense.
In rushing for 116 yards, Bradshaw became only the second back in 46 games, including the playoffs, to rush for 100 yards or more against the 49ers' vaunted defense.
Also, Bradshaw's third-quarter touchdown run marked the first rushing touchdown allowed at home by the 49ers in 13 games, dating to the 2010 season.
Coincidentally, the last player to rush for 100 yards or more against the 49ers comes to town Thursday, when Marshawn Lynch and the Seattle Seahawks invade Candlestick Park in a clash for first place in the NFC West.
Suffice it to say, the 49ers don't need any more reason to be fired up when it comes to run defense.
"They had a couple where they gashed us a couple of times," 49ers safety Donte Whitner said of the Giants.
It's not time to panic and make radical changes, though, he added. After all, the 49ers entered Sunday's game seventh in the league against the run at an average of 81.4 yards, tied for sixth at an average of 3.5 yards per carry and tied for second with one touchdown allowed.
"Our front is one of the best fronts in the NFL, especially stopping the run with seven (defenders)," Whitner said. "So, today they found a couple of creases. It's nothing to worry about. We'll get it fixed."
Brooks said it doesn't matter when the yards come on the ground, even if it's after the outcome has been decided; the 49ers take it personally.
The issue is something that will be addressed in practice in the days leading up to the Seahawks game and resolved in short order.
"We have to do something about that," Brooks said. "We can't let teams walk all over us like that. We take pride in our defense; we take pride in stopping the run. We just didn't accomplish any of that today."
Bradshaw started slowly, with only 23 yards on 11 carries in the first half.
Coach Jim Harbaugh credited the run defense for keeping the 49ers within striking distance, when the 49ers held the Giants without a first down and forced them to settle for a field goal to make it 23-3 in the third quarter.
Of course, the Giants salted away the game afterward, with Bradshaw and Wilson churning out yards time and again in the fourth quarter.
"It's one of those games," Brooks said. "I don't even know what to say."
The stats said it all.
