Head coach Kyle Shanahan didn't seem to know if anyone from the San Francisco 49ers would be in Atlanta on Saturday for the league-organized workout of quarterback Colin Kaepernick.

"I don't know," Shanahan said when asked if the 49ers would be there. "I would guess, but not something I've asked [the scouts or personnel staff] yet."

It turns out, someone from the 49ers will be there, according to Matt Barrows of The Athletic.

Added Shanahan: "I don't know at all the schedule of our personnel guys. I mean, during the season, during their offseason, it's not their offseason, but their main time is draft time, but yeah, they are all over the place. We got guys all over, so I'm sure that someone can be there. I don't think that would be too tough."

Kaepernick, 32, last played in the NFL during the 2016 season and officially opted out of his contract with the 49ers on March 3, 2017, shortly after the arrival of general manager John Lynch and head coach Kyle Shanahan, who had no intention of retaining the veteran quarterback. He has remained unsigned since.

San Francisco made Kaepernick a second-round draft pick in 2011. He completed 59.8 percent of his passes for 12,271 yards with 72 touchdowns and 30 interceptions in his five NFL seasons.

Kaepernick's name dominated headlines during the 2016 season because of his refusal to stand during the national anthem. That protest is believed by many to be one potential reason why most NFL clubs have steered clear of the controversial figure.

Kaepernick, along with former teammate Eric Reid, now with the Carolina Panthers, filed a grievance in October of 2017 under the collective bargaining agreement, alleging collusion by NFL teams against signing him. The two reached a settlement with the NFL on February 15.

Multiple sources have stated that Saturday's workout is not part of that settlement, and some, like ESPN's Adam Schefter, remain skeptical if the workout will even take place.

If it does take place, representatives from the 49ers plan to be there.
