The play initially was ruled an incompletion on the field, but replay clearly showed Hooper had it for a touchdown before it was pulled out of his arms.
As Titans coach Mike Vrabel pulled out his red flag, the replay assistant upstairs reversed the call to a touchdown.
Tannehill’s pass into a tight window completed a five-play, 63-yard drive after the Packers had pulled to within three points.
The Titans entered the game without a fourth quarter touchdown this season and needed only five seconds into the fourth quarter Thursday night to get into the end zone.
Tannehill 20-of-24 for 263 yards and two touchdowns, with Hooper catching four passes for 36 yards and two scores. Robert Woods has six receptions for 69 yards.
