Eifert, who left the field with his arm dangling by his side, with what was believed to be a wrist or elbow injury, turned out to be a neck stinger.
Bengals' bloodhound, Joe Reedy, via his official twitter account:
Eifert out for rest of the game due to neck stinger

The boy from Notre Dame returned for a few more plays but was declared out after he could not continue. Eifert had one reception for six yards before his day was cut short.
TE is having a fine rookie season with 39 receptions for 445 yards and two touchdowns. Eifert started all 15 games this season for the Cincy Cats.
Eifert's status for Sunday's regular season finale is unclear.
