More than 24 organizations are expected to be represented at Kaepernick's showcase Saturday at the Atlanta Falcons' training complex, sources told Adam Schefter of ESPN.
The Arizona Cardinals, Atlanta Falcons, Cleveland Browns, Denver Broncos, Detroit Lions, Miami Dolphins, New England Patriots, New York Giants, New York Jets, Tampa Bay Buccaneers, and Washington Redskins were the original 11 teams announced by the league.
One club that can be ruled out is the Dallas Cowboys, as owner Jerry Jones said Friday that his team is happy with its quarterback situation.
"We're not gonna have anybody there. We'll look at the tape if we need any information there. We really like our quarterbacks," Jones said, according to Jon Machota of The Athletic.
The league has not provided Kaepernick with the identity of the receivers who'll be catching passes, so the quarterback has arranged to bring his own wideouts to the workout, a source told Pro Football Talk's Mike Florio.
All 32 franchises have been invited to send representatives to see Kaepernick, who has been out of the league since 2017 after he began protesting social injustices by kneeling during the national anthem.
