Colin Kaepernick wants everyone to know he's still NFL ready ... and he's showing off his rocket arm during a training session in Houston.
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.
