Georgia RB Nick Chubb ties Herschel Walker's mark of 12 consecutive 100-yard rushing games as the No. 7 Bulldogs beat Southern 48-6. (0:53)

Running back Nick Chubb rushed for over 100 yards in the second half of Georgia's game against Southern on Saturday, giving him 12 consecutive games with over 100 yards rushing to tie Herschel Walker's school mark.

Chubb finished with 131 yards in No. 7 Georgia's 48-6 victory in Athens, Georgia.

Georgia was limited to 35 rushing yards in the first half Saturday, its fewest in a half since a loss to Vanderbilt in 2013. Chubb, who had 31 rushing yards at halftime, then gained 35 yards on his first three second-half carries. He eclipsed the 100-yard mark with a 49-yard touchdown run, his second rushing touchdown of the game. He also had a 24-yard touchdown reception.

Chubb said the Georgia linemen gave him a pep talk at the half.

"With them being more excited than I was, I knew we had to get it," he said.

Georgia left tackle John Theus said he thinks Chubb's streak "is huge."

"Right after he scored the (49-yard) TD, I told him congrats," Theus said. "He definitely makes us look good."

Chubb's 12th consecutive 100-yard effort ties him for the longest active streak in FBS with Toledo's Kareem Hunt. Toledo plays Arkansas State later Saturday.

For Chubb it's the second time in his career he's surpassed 100 yards in the second half of a game. He rushed for 188 yards in the second half against Louisville in last season's Belk Bowl.

Entering Saturday's games, Chubb had rushed for a FBS-high 1,791 yards since taking over as Georgia's starting running back in Week 7 last season.
