The NFL organized the private session in Atlanta, which will involve on-field work and an interview, according to ESPN's Adam Schefter.
Schefter reported that all 32 teams are invited, and a video of the workout and interview will be made available as well.
The 32-year-old Kaepernick hasn't played since the 2016 season.
"I've been in shape and ready for this for 3 years, can't wait to see the head coaches and GMs on Saturday," he said after hearing about the opportunity.
