Kaepernick hit the field with Josh Hidalgo -- Head of Sports Performance at William Paterson University -- and threw some darts with a team of pass catchers.

Hidalgo says he's been training Kaep every single day since January 2017 -- adding, "We haven't stopped throwing, training and preparing."

"To say he's dedicated is an understatement ... Even when we’re traveling we put in that work."

Kaepernick hasn't taken a snap in the NFL since 2016 -- before he parted ways with the San Francisco 49ers.

Kaep has said he wants to get back in the league and compete for a starting job again -- and now he wants the world to see he's still got the talent that took him to the Super Bowl.
