Colin Kaepernick continues to show NFL teams his desire to extend his football career. 

ESPN's Adam Schefter reported Tuesday that NFL teams were informed the former 49ers quarterback will hold a private workout Saturday in Atlanta. Kaepernick will showcase his current shape and football skills, as well as answer any questions. 

All NFL teams have been invited to attend, according to Schefter, and video of the workout and interview will be made available to every franchise.

Kaepernick himself confirmed the workout, tweeting that he has been "ready for this for 3 years."

I’m just getting word from my representatives that the NFL league office reached out to them about a workout in Atlanta on Saturday. I’ve been in shape and ready for this for 3 years, can’t wait to see the head coaches and GMs on Saturday.

Later Tuesday afternoon, Schefter added more details about the workout, which includes some odd stipulations.

As Colin Kaepernick tweeted, the NFL didn't inform his reps of Saturday's workout in Atlanta until this morning. Kaepernick's reps asked for workout to be on a Tuesday, the day of most workouts, but NFL said it had to be this Saturday. He asked for a later Saturday; NFL said no.

Colin Kaepernick's reps asked the NFL for a list of personnel executives and coaches who would be attending the workout; they are hoping and expecting the NFL to submit the list of personnel executives and coaches that will attend on Saturday.

Kaepernick, 32, last played in the NFL in 2016 with the 49ers. The six-year pro began kneeling during the national anthem in the 2016 preseason to protest racial and social injustices, as well as police brutality to African Americans. 

Kaepernick underwent shoulder surgery going into the 2016 season and had to work his way back to health. He appeared in 12 games that season -- starting 11 -- and threw 16 touchdowns to four interceptions. Kaepernick also added two more touchdowns on the ground.

The former 49ers QB threw for 2,241 yards and rushed for another 468 the last time he played in the NFL. Kaepernick has 12,271 career passing yards, 2,300 career rushing yards and 85 total touchdowns over his six-year career.

In February, Kaepernick and former 49ers safety Eric Reid, who joined Kaepernick's protest by kneeling as well in 2016, resolved their pending grievances against the NFL. Reid currently is in his second season with the Carolina Panthers. He continues to kneel during the anthem. 

Kaepernick has posted videos to social media of his workouts, and his representatives told ESPN he has been "working out five days a week, for three years, in preparation to play again."

It’s never too early to look ahead when you’re talking NFL draft. 

Looking ahead to next year’s event, CBS Sports sees the 49ers addressing the secondary with their first-round selection. R.J. White predicts the 49ers will select Israel Mukuamu from South Carolina at No. 31 overall.

Mukuamu has the height at 6-foot-4 to keep up with any of the NFL’s tallest and most athletic wideouts, and was named to the All-SEC second team in 2019 as a sophomore.

It would be the third consecutive year general manager John Lynch chose to select a South Carolina product in the first two rounds of the NFL draft, after taking wideout Deebo Samuel in 2019 and defensive lineman Javon Kinlaw in April.

The 49ers have three cornerbacks who could enter free agency next offseason, so the position should be a priority for Lynch after the 2020 campaign.

Mukuamu famously picked off former Georgia quarterback and Buffalo Bills fourth-round pick Jake Fromm three times this past season, including one that was aided by a Kinlaw pressure.

Bay Area native Tom Brady didn’t start out so hot in Sunday’s “The Match,” but managed to make the most impressive shot of the day on the seventh hole. The event, also featuring former NFL MVP Peyton Manning and PGA icons Tiger Woods and Phil Mickelson, was a smashing success, raising over $20 million for coronavirus relief efforts and becoming the most-watched golf event in cable television history.

Fox Sports’ Colin Cowherd talked through some potential duos who should participate in the next iteration of the event, and thinks Brady could take on former teammate and 49ers quarterback Jimmy Garoppolo next time around.

Brady and his partner Woods were swiftly defeated by the Manning-Mickelson pairing on Sunday, and likely would be seeking some revenge in a showdown with Garoppolo. The two also have the obvious history of being in New England together before a controversial trade with the 49ers in 2017.

Of course, 49ers general manager John Lynch did admit this offseason that the front office did due diligence on Brady during his free agency, but the six-time Super Bowl champ opted to join the Tampa Bay Buccaneers. Garoppolo has taken a plethora of shots this offseason for his play in Super Bowl LIV, where the Niners blew a 10-point lead and lost to the Kansas City Chiefs.

There doesn’t seem to be much evidence of Garoppolo’s golf game on the internet, but it’s hard to imagine he hasn’t hit the links a few times in his life. He couldn’t play much worse than Brady started out through six holes on Sunday.

Underlying tension between the two could come to the surface over the course of 18 holes together, but Garoppolo and Brady never have given any public indication the two have beef.

A matchup between the two could provide some laughs, but there are plenty of other duos more compelling for the next event.
