Stafford was fined $7,500 for unnecessary roughness after he grabbed Bears defensive back D.J. Moore by the helmet in the fourth quarter, an NFL spokesman told Reuters.
Moore drew a $15,000 fine for striking Stafford in retaliation. He also was ejected from the game, won 37-13 by the Bears.
Detroit defensive tackle Nick Fairley was also docked $15,000 for unnecessarily driving Bears quarterback Jay Cutler to the ground.
Guard Rob Sims and defensive end Kyle Vanden Bosch of the Lions were each fined $7,500 for striking an opponent late, and Bears receiver Earl Bennett was assessed a $10,000 fine.
His infraction? For the second time this season, he wore dominantly orange shoes, a uniform violation, the NFL said.
“I asked (team mates) ‘Should I wear the orange shoes again?'” Bennett told reporters.
“One of them (team mates) was like ‘most definitely, I’ll take care of it.’ So that’s how it went down,” Bennett said.
He was fined $5,000 for the first violation.
