The Giants signed Jiles on Friday, Dan Salomone of the team's official site reports.
Jiles brought in 54 passes for 1,081 yards yards and 13 touchdowns in just 10 games after transferring to West Florida in 2023. However, he'll have to prove capable of managing the big leap in competition from what he faced in the Gulf South Conference to have a chance at earning playing time at the NFL level.
