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."

49ers broadcaster Tim Ryan was suspended for one game after comments made about Baltimore Ravens quarterback Lamar Jackson following Sunday’s loss.

“He’s really good at that fake, Lamar Jackson, but when you consider his dark skin color with the dark football with a dark uniform, you could not see the thing,” Ryan said on the show (H/T The San Francisco Chronicle).

The comments created a social media firestorm, but Ravens head coach John Harbaugh isn’t interested in furthering the controversy.

“I don’t really know too much about it or understand the context of it. It’s not relevant to what we’re trying to accomplish right now,” Harbaugh said, via Jamison Hensley of ESPN.com.

Former 49ers defensive end Dennis Brown will replace Ryan on Sunday’s broadcast in New Orleans.

BRADENTON, Fla. – Marcell Harris on Sunday will be back where he ended his rookie season with the 49ers.

Harris will take over as the 49ers’ starter at strong safety with Jaquiski Tartt out for at least one game after sustaining cracked ribs in the team’s 20-17 loss to the Baltimore Ravens in Week 13.

Tartt and backup defensive tackle Jullian Taylor (elbow) have been ruled out for the 49ers’ game Sunday against the New Orleans Saints.

Two of the 49ers’ seldom-used wide receivers, Marquise Goodwin and Dante Pettis, are listed as questionable, along with left tackle Joe Staley. Goodwin has knee and foot issues, according to the team, while Pettis has already missed one game with a knee injury.

Staley has missed three games after surgery to repair a fractured and dislocated finger. He is expected to play Sunday.

All other 49ers players, including Dee Ford and Richard Sherman, will be available for Sunday’s game.

Harris started the final five games of his rookie season after being a sixth-round draft pick from Florida in 2018. He did not earn a spot on the team’s 53-man roster at the beginning of this season. Harris was promoted from the practice squad in October and has appeared in nine games this season.

“I’m real happy for Marcell,” coach Kyle Shanahan said on "49ers Game Plan," which airs Saturday at 7 p.m. on NBC Bay Area (Ch. 3). “He’s gone come a long way, in that he was a very good college player, tore his Achilles his senior year, which really hurt him. That’s why we were able to get him in the draft. It affected him his whole rookie year.

"He’s been able to string together about eight months where he has been healthy, and when you’re made of the right stuff, you have the talent and you can stay healthy, you usually just need the time.”

Harris took over for Tartt on Sunday and made one of the top plays in the game when he took the ball away from Ravens quarterback Lamar Jackson on a running play to create a turnover.
