Pettis (shoulder) was forced out of Monday's 20-17 loss to the Chiefs, Dan Salomone of the Giants' official site reports.
Pettis was injured during the first half of Monday's loss while attempting to recover his own mishandled punt return. The severity of the 2018 second-round pick's injury remains undisclosed at this time. Heading into Week 8, Pettis had put together back-to-back games with five receptions.
