Tied at 24 with less than two minutes to go in regulation, the Colts took over on offense on their own 8-yard line. Wentz was about to get sacked for a safety. While facing that pressure, Wentz attempted to make a left-handed pass that ended up in the hands of Titans rookie Elijah Molden. Molden scored a 2-yard touchdown to put Tennessee ahead 31-24 after a successful extra point.

On the ensuing Colts offensive drive, Wentz connected with wide receiver Michael Pittman Jr. for a 37-yard gain. After Ashton Dulin drew a 42-yard pass interference penalty, running back Jonathan Taylor ran in a 1-yard TD with 22 seconds to go to tie the game.
