Mike Reiss of ESPN reports the Patriots will sign Gauthier, pending a physical and COVID-19 test.
The Patriots originally signed Gauthier as an undrafted free agent out of the University of Miami in 2019. He spent time on their practice squad.
Gauthier, who has never appeared in a regular-season game, signed with the Jaguars’ 53-player roster Dec. 10.
The Jaguars cut him Saturday.
