Grupe made just one of three field-goal attempts and his lone extra-point try in New Orleans' 24-10 loss to the Falcons on Sunday.
It's been a trying season for Grupe, who is now just 18 of 26 on field-goal tries this season. His misses against Atlanta came from 38 and 47 yards. Grupe is likely on thin ice in New Orleans after the team flirted with kickers earlier this season.
