Smith, appearing on ESPN Radio’s “Golic and Wingo” show Wednesday morning, said he spoke with people “directly” regarding Kaepernick. 

“There’s only two things that will prevent Colin Kaepernick from having a job in the NFL,” Smith said. “That is one, if he shows up Saturday and can’t throw the ball on the damn football field, he’s throwing the ball in the stands. He’d have to be that God awful not to get a legitimate look and potentially have a job next week.”

He continued to explain the second thing, which is that Kaepernick needs to stay quiet in the days leading up to the event.

“The other thing that could be a hindrance is if he opens his damn mouth and starts talking too much, and scares these teams off and gives them the indication that more of what transpired, that led to all of this, will continue forward,” Smith said. “Only Colin Kaepernick can mess it up. It’s beyond all of that other stuff now. He needs to shut up. No Instagram. No Twitter. No anything. Show up Saturday, work out. Don’t say a word before then.”

Smith said if Kaepernick can do all of that, he’ll have an NFL job “within the next week or two.”

The former 49ers QB did release a brief statement on Tuesday, essentially just confirming he’ll show up for the workout in Atlanta.

As for what to expect Saturday, NFL Media’s Ian Rapoport shared details Wednesday morning.

If a team isn’t able to send someone to the workout, every part will be recorded to share with NFL teams.

The league sent the following memo to every team on Tuesday:

While every team is invited, it’s not clear just how many teams will send someone to attend. ESPN’s Josina Anderson reported Tuesday night a team in the NFC will show up because, “We have nothing to lose by attending Kaepernick’s workout, but I still think for us it would just be an information-gathering trip.”

Anderson also reported there is interest from the Cowboys in Kaepernick’s workout.

Kaepernick, 32, hasn’t played in the league since the 2016 season with the 49ers. In 12 games, he had a 16-4 TD-INT ratio, averaging 186.8 passing yards per game. He also ran for 468 yards and two touchdowns. His 88.9 quarterback rating ranks 23rd all time among QBs with at least 1,500 career pass attempts.
