Mullens last played for the Minnesota Vikings, joining them in 2022. He now heads to the much warmer climate alongside Grant Udinski, who was the assistant offensive coordinator and assistant quarterbacks coach for the Vikings in 2024 and is now the Jaguars offensive coordinator.

Mullins is joining the team on a two-year, $6.5 million contract with $3 million in guaranteed money. He spent time with new Jaguars offensive coordinator Grant Udinski in Minnesota and now joins Jacksonville to be Trevor Lawrence's backup.

The Jacksonville Jaguars are focused on the 2025 NFL season, and to do so, they have signed a backup QB for Trevor Lawrence. It’s a time of great movement in the NFL, as most teams are slowly starting to finalize their rosters.
