Colin Kaepernick will hold a private workout for NFL teams on Saturday in Atlanta. The session will include on-field work and an interview.
Several teams have inquired about Kaepernick's current readiness to play football.
The memo, which was sent to NFL teams, says: "Earlier this year, we discussed some possible steps with his representatives and they recently emphasized his level of preparation and that he is ready to work out for clubs and be interviewed by them. We have therefore arranged this opportunity for him to work out, and for all clubs to have the opportunity to evaluate his current readiness and level of interest in resuming his NFL career."
Kaepernick turned 32 on Nov. 3 and hasn't played in the NFL since 2016.
Last month, Kaepernick's representatives said he has been "working out five days a week, for three years, in preparation to play again" but that the opportunity hasn't presented itself.
