Clayborn sacked Cowboys quarterback Dak Prescott six times in a rampaging display during the Falcons 27-7 win, the second-best single-game performance in NFL history.
For Clayborn the sacks translated into a hefty bonus, as it took him past eight sacks for the season, activating an incentive clause in his contract.
"I would have never imagined it," Clayborn said after his sack spree.
"It's crazy. Our tackles were flushing him out and I was coming off the edge."
According to the NFL Network, Clayborn could even add to his bonus if he registers further sacks this season.
Two more would earn him another $500,000 while four more would net an extra $1.25 million.
