A memo about the workout went out to all 32 teams Tuesday.
Kaepernick started a league-wide movement to kneel during the national anthem to protest social and racial injustices and police brutality. He settled a grievance with the NFL in February, in which he accused the league of blacklisting him because of the protests.
The workout, which will include an interview, measurements and other quarterback drills, will be recorded and provided to all league teams.
Other teams have not publicly stated whether they will attend the workout, which will be closed to the public and the media.
The Falcons will have a walk-through Saturday before leaving in the afternoon for Charlotte to play the Panthers Sunday.
