Adrian Clayborn has taken advantage of an injury on the Dallas offensive line to post the most productive pass-rush game in Atlanta Falcons history.

Clayborn's six sacks of Dallas quarterback Dak Prescott broke the record of five set by Chuck Smith and unofficially shared by Claude Huimphrey.

Smith had five sacks against the Saints on Oct. 12, 1997.

Clayborn's sixth sack, early in the fourth quarter, also produced his second forced fumble of the game. He had a forced fumble and recovery late in the first half.

Clayborn consistently beat Cowboys backup left tackle Chaz Green for the record.

It's the most sacks in a game by a NFL player this season and is tied for the second-highest total in league history.

Green started when Cowboys regular left tackle Tyron Smith was held out with a back/groin injury.

Clayborn began to torment Green when he recorded two sacks of Prescott on the Cowboys’ opening drive.

Clayborn matched Smith’s record with his fifth sack, again beating Green, early in the fourth quarter.

The Falcons say Humphrey, the Hall of Famer, had two five-sack games before sacks became an official statistic.
